1. There is not the slightest evidence that the year in which Sennacherib besieged Jerusalem was a Sabbatic year, or that the following year was the Jubilee. No mention is made of this in the history, nor is it possible to prove it from any part of the sacred narrative.

2. It is still difficult to see, even if it were so, how that which was to occur two or three years after the event, could be a sign to Hezekiah then of the truth of what Isaiah had predicted.

Rosenmuller suggests that the two years in which they are mentioned as sustained by the spontaneous productions of the earth were the two years in which Judea had been already ravaged by Sennacherib, and that the third year was the one in which the prophet was now speaking, and that the prediction means that in that very year they would be permitted to sow and reap. In the explanation of the passage, it is to be observed that the word 'sign' is used in a variety of significations. It may be used as an indication of anything unseen Genesis 1:14; or as a military ensign Numbers 2:2; or as a sign of something future, an omen Isaiah 8:18; or as a token, argument, proof Genesis 17:2; Exodus 31:13. It may be used as a sign or token of the truth of a prophecy; that is, when some minor event furnishes a proof that the whole prophecy would be fulfilled Exodus 3:12; 1 Samuel 2:34; 1 Samuel 10:7, 1 Samuel 10:9. Or it may be used as a wonder, a prodigy, a miracle Deuteronomy 4:34; Deuteronomy 6:22.

In the case before us, it seems to mean that, in the events predicted here, Hezekiah would have a token or argument that the land was completely freed from the invasion of Sennacherib. Though a considerable part of his army would be destroyed; though the monarch himself would be compelled to flee, yet Hezekiah would not from that fact alone have the assurance that he would not rally his forces, and return to invade the land. There would be every inducement arising from disappointment and the rage of defeat for him to do it. To compose the mind of Hezekiah in regard to this, this assurance was given, that the land would be quiet, and that the fact that it would remain quiet during the remainder of that year, and to the third year would be a sign, or demonstration that the Assyrian army was entirely withdrawn, and that all danger of an invasion was at an end. The sign, therefore, does not refer so much to the past, as to the security and future prosperity which would be consequent thereon.

It would be an evidence to them that the nation would be safe, and would be favored with a high degree of prosperity (see Isaiah 37:31-32). It is possible that this invasion took place when it was too late to sow for that year, and that the land was so ravaged that it could not that year be cultivated. The harvests and the vincyards had been destroyed; and they would be dependent on that which the earth had spontaneously produced in those parts which had been untilled. As it was now too late to sow the land, they would be dependent in the following year on the same scanty supply. In the third year, however, they might cultivate their fields securely, and the former fertility would be restored.

Such as groweth of itself - The Hebrew word here (ספיח sâphı̂yach), denotes grain produced from the kernels of the former year, without new seed, and without cultivation. This, it is evident, would be a scanty supply; but we are to remember that the land had been ravaged by the army of the Assyrian.

That which springeth of the same - The word used here (שׁחיס shâchiys), in the parallel passage in 2 Kings 19:29 (סחישׁ sâchiysh), denotes that which grows of itself the third year after sowing. This production of the third year would be of course more scanty and less valuable than in the preceding year, and there can be no doubt that the Jews would be subjected to a considerable extent to the evils of want. Still, as the land would be quiet; as the people would be permitted to live in peace; it would be a sign to them that the Assyrian was finally and entirely withdrawn, and that they might return in the third year to the cultivation of their land with the assurance that this much-dreaded invasion was not again to be feared.

And in the third year - Then you may resume your agricultural operations with the assurance that you shall be undisturbed. Your two years of quiet shall have been a full demonstration to you that the Assyrian shall not return, and you may resume your employments with the assurance that all the evils of the invasion, and all apprehension of danger, are at an end.

sign—a token which, when fulfilled, would assure him of the truth of the whole prophecy as to the enemy's overthrow. The two years, in which they were sustained by the spontaneous growth of the earth, were the two in which Judea had been already ravaged by Sennacherib (Isa 32:10). Thus translate: "Ye did eat (the first year) such as groweth of itself, and in the second year that … but in this third year sow ye," &c., for in this year the land shall be delivered from the foe. The fact that Sennacherib moved his camp away immediately after shows that the first two years refer to the past, not to the future [Rosenmuller]. Others, referring the first two years to the future, get over the difficulty of Sennacherib's speedy departure, by supposing that year to have been the sabbatical year, and the second year the jubilee; no indication of this appears in the context.

ye shall eat this year such as groweth of itself: and the second year that which springeth of the same: and in the third year sow ye, and reap and plant vineyards, and eat the fruit thereof: all which was very wonderful; for whereas, either through the invasion of the land, and the siege of the city, they could not till their land as they had used to do, or what was upon it was destroyed or eaten up by the Assyrian army; and yet, through the wonderful providence of God, the earth of its own accord yielded that very year a sufficiency for them; and though the second year was, as it is thought, a sabbatical year, when the land had rest, and by the law was not to be tilled, yet it also produced of itself what was sufficient for their support; and then the third year being entirely free from the enemy, and all fears of his return, they go about their business as formerly, to sowing and reaping corn, and planting vineyards, and enjoying the fruit of their labours; all which falling out according to this prediction, must greatly confirm the mind of Hezekiah, and make him easy as to any future attempt upon him he might fear. The Vulgate Latin version renders the second clause, "ye shall eat apples the second year"; and so Symmachus, but without foundation.

(y) God gives signs after two sorts: some go before the thing as the signs that Moses worked in Egypt, which were for the confirmation of their faith, and some go after the thing, as the sacrifice, which they were commanded to make three days after their departure: and these latter are to keep the blessings of God in our remembrance, of which sort this here is.

(z) He promises that for two years the ground would feed them of itself.
