Numbers 15:39

"And it shall be to you for a tassel," i.e., the fastening of the tassel with the dark blue thread to the corners of your garments shall be to you a tassel, "that ye, when ye see it, may remember all the commandments of Jehovah, and do them; and ye shall not stray after your hearts and your eyes, after which ye go a whoring." The zizith on the sky-blue thread was to serve as a memorial sign to the Israelites, to remind them of the commandments of God, that they might have them constantly before their eyes and follow them, and not direct their heart and eyes to the things of this world, which turn away from the word of God, and lead astray to idolatry (cf. Pro 4:25-26). Another reason for these instructions, as is afterwards added in Num 15:40, was to remind Israel of all the commandments of the Lord, that they might do them and be holy to their God, and sanctify their daily life to Him who had brought them out of Egypt, to be their God, i.e., to show Himself as God to them.

This chapter, which is mostly concerning sacrifice and offering, comes in between the story of two rebellions (one ch. 14, the other ch. 16), to signify that these legal institutions were typical of the gifts which Christ was to receive even for the rebellious, Psa 68:18. In the foregoing chapter, upon Israel's provocation, God had determined to destroy them, and in token of his wrath had sentenced them to perish in the wilderness. But, upon Moses' intercession, he said, "I have pardoned;" and, in token of that mercy, in this chapter he repeats and explains some of the laws concerning offerings, to show that he was reconciled to them, notwithstanding the severe dispensation they wee under, and would not unchurch them. Here is, I. The law concerning the meat-offerings and drink-offerings (Num 15:1-12) both for Israelites and for strangers (Num 15:13-16), and a law concerning the heave-offerings of the first of their dough (Num 15:17-21). II. The law concerning sacrifices for sins of ignorance (Num 15:22-29). III. The punishment of presumptuous sins (Num 15:30, Num 15:31), and an instance given in the sabbath-breaker (Num 15:32-36). IV. A law concerning fringes, for memorandums, upon the borders of their garments (Num 15:37, etc.).
