Num 15:39-41
“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. Rebellion of Korah’s Company - Numbers 16:1-40(17:1-5)
The sedition of Korah and his company, with the renewed sanction of the Aaronic priesthood on the part of God which it occasioned, is the only important occurrence recorded in connection with the thirty-seven years’ wandering in the wilderness. The time and place are not recorded. The fact that the departure from Kadesh is not mentioned in Num 14, whilst, according to Deu 1:46, Israel remained there many days, is not sufficient to warrant the conclusion that it took place in Kadesh. The departure from Kadesh is not mentioned even after the rebellion of Korah; and yet we read, in Num 20:1, that the whole congregation came again into the desert of Zin to kadesh at the beginning of the fortieth year, and therefore must previously have gone away. All that can be laid down as probable is, that it occurred in one of the earliest of the thirty-seven years of punishment, though we have no firm ground even for this conjecture.
