(11) Take . . . in vain.—Literally, Thou shalt not put the name of Jehovah thy God to vanity: i.e., to anything that is false, or hollow, or unreal. Primarily, it is false swearing that is forbidden here; but the extension of the principle to vain and rash swearing, or the light use of the Name without real cause, is sufficiently obvious.

Deuteronomy 5:11. Thou shalt not take the name of the Lord thy God in vain — Hast thou never used the name of God unless on solemn and weighty occasions? Hast thou then used it with the deepest awe? Hast thou duly honoured his word, his ordinances, his ministers? Hast thou considered all things as they stand in relation to him, and seen God in all? Hast thou looked upon heaven as God’s throne? Upon earth as God’s footstool? On every thing therein as belonging to the great King? On every creature as full of God?

5:6-22 There is some variation here from Ex 20 as between the Lord's prayer in Mt 6 and Lu 11. It is more necessary that we tie ourselves to the things, than to the words unalterably. The original reason for hallowing the sabbath, taken from God's resting from the work of creation on the seventh day, is not here mentioned. Though this ever remains in force, it is not the only reason. Here it is taken from Israel's deliverance out of Egypt; for that was typical of our redemption by Jesus Christ, in remembrance of which the Christian sabbath was to be observed. In the resurrection of Christ we were brought into the glorious liberty of the children of God, with a mighty hand, and an outstretched arm. How sweet is it to a soul truly distressed under the terrors of a broken law, to hear the mild and soul-reviving language of the gospel!Compare Exodus 20 and notes.

Moses here adopts the Ten Words as a ground from which he may proceed to reprove, warn, and exhort; and repeats them, with a certain measure of freedom and adaptation. Our Lord Mark 10:19 and Paul Ephesians 6:2-3 deal similarly with the same subject. Speaker and hearers recognized, however, a statutory and authoritative form of the laws in question, which, because it was familiar to both parties, needed not to be reproduced with verbal fidelity.

6-20. I am the Lord thy God—The word "Lord" is expressive of authority or dominion; and God, who by natural claim as well as by covenant relation was entitled to exercise supremacy over His people Israel, had a sovereign right to establish laws for their government. [See on [115]Ex 20:2.] The commandments which follow are, with a few slight verbal alterations, the same as formerly recorded (Ex 20:1-17), and in some of them there is a distinct reference to that promulgation. No text from Poole on this verse.

I am the Lord thy God,.... This is the preface to the ten commandments, and is the same with that in Exodus 20:2; see Gill on Exodus 20:2, and those commands are here delivered in the same order, and pretty near in the same words, with a little variation, and a few additions; which I shall only observe, and refer to Exodus 20:1 for the sense of the various laws. Thou shalt not take the name of the LORD thy God in vain: for the LORD will not hold him guiltless that taketh his name in vain.
