exchanged, and could not be redeemed. The words “whatsoever passeth under the rod” may be explained from the custom of numbering the flocks by driving the animals one by one past the shepherd, who counted them with a rod stretched out over them (cf. Jer 33:13; Eze 20:37). They mean everything that is submitted to the process of numbering, and are correctly explained by the Rabbins as referring to the fact that every year the additions to the flock and herd were tithed, and not the whole of the cattle. In these directions the tithe is referred to as something well known. In the laws published hitherto, it is true that no mention has been made of it; but, like the burnt-offerings, meat-offerings, and peace-offerings, it formed from time immemorial an essential part of the worship of God; so that not only did Jacob vow that he would tithe for the Lord all that He should give him in a foreign land (Gen 28:22), but Abraham gave a tenth of his booty to Melchizedek the priest (Gen 14:20). Under these circumstances, it was really unnecessary to enjoin upon the Israelites for the first time the offering of tithe to Jehovah. All that was required was to incorporate this in the covenant legislation, and bring it into harmony with the spirit of the law. This is done here in connection with the holy consecrations; and in Num 18:20-32 instructions are given in the proper place concerning their appropriation, and further directions are added in Deu 12:6, Deu 12:11; Deu 14:22. respecting a second tithe. - The laws contained in this chapter are brought to a close in v. 34 with a new concluding formula (see Lev 26:46), by which they are attached to the law given at Sinai.
