So far as the occurrence itself is concerned, there can hardly be any need to remark, that the natural interpretation which has lately been attempted by Ewald, viz., that Moses had laid several almond rods in the holy place, which had just been freshly cut off, that he might see the next day which of them would flower the best during the night, is directly at variance with the words of the text, and also with the fact, that a rod even freshly cut off, when laid in a dry place, would not bear ripe fruit in a single night. The miracle which God wrought here as the Creator of nature, was at the same time a significant symbol of the nature and meaning of the priesthood. The choice of the rods had also a bearing upon the object in question. A man's rod was the sign of his position as ruler in the house and congregation; with a prince the rod becomes a sceptre, the insignia of rule (Genesis 49:10). As a severed branch, the rod could not put forth shoots and blossom in a natural way. But God could impart new vital powers even to the dry rod. And so Aaron had naturally no pre-eminence above the heads of the other tribes. But the priesthood was founded not upon natural qualifications and gifts, but upon the power of the Spirit, which God communicates according to the choice of His wisdom, and which He had imparted to Aaron through his consecration with holy anointing oil. It was this which the Lord intended to show to the people, by causing Aaron's rod to put forth branches, blossom, and fruit, through a miracle of His omnipotence; whereas the rods of the other heads of the tribes remained as barren as before. In this way, therefore, it was not without deep significance that Aaron's rod not only put forth shoots, by which the divine election might be recognised, but bore even blossom and ripe fruit. This showed that Aaron was not only qualified for his calling, but administered his office in the full power of the Spirit, and bore the fruit expected of him. The almond rod was especially adapted to exhibit this, as an almond-tree flowers and bears fruit the earliest of all the trees, and has received its name of שׁקד, "awake," from this very fact (cf. Jeremiah 1:11).

God then commanded (Numbers 17:10, Numbers 17:11) that Aaron's rod should be taken back into the sanctuary, and preserved before the testimony, "for a sign for the rebellious, that thou puttest an end to their murmuring, and they die not." The preservation of the rod before the ark of the covenant, in the immediate presence of the Lord, was a pledge to Aaron of the continuance of his election, and the permanent duration of his priesthood; though we have no need to assume, that through a perpetual miracle the staff continued green and blossoming. In this way the staff became a sign to the rebellious, which could not fail to stop their murmuring.
