Leviticus 7:16

“But if the sacrifice of his offering be a vow, etc.] Be on account of a vow made, as, that if he was favoured with such and such benefits, or delivered out of such and such troubles and distresses, then he would offer such a sacrifice: or a voluntary offering; without any condition or obligation; what from the mere motion of his mind he freely offered, not being directed to it by any command of God, or under any necessity from a vow of his own, and without any view to; any future good to be enjoyed: Aben Ezra describes both the one and the other thus; a “vow” which he uttered with his lips in his distresses, a “voluntary offering”, which his spirit made him willing to bring, a sacrifice to…”

“The vow-offering appears to have been a peace-offering vowed upon a certain condition; the voluntary-offering, one offered as the simple tribute of a devout heart rejoicing in peace with God and man offered on no external occasion (compare Leviticus 22:17-25). return to 'Top of Page'”

“A vow - Offered in performance of a vow, the man having desired some special favour from God, and vowed the sacrifice to God if he would grant it. On the morrow also - Which was not allowed for the thank - offering. Leviticus 7:18”

“7:16-18 In contrast to the “peace offering of thanksgiving,” which was presented as an expression of thanks to the Lord (7:12-15), the offering to fulfill a vow related to a vow made by a worshiper. The festive meal that followed was more relaxed and could extend into the next day. However, because the vow offering involved a vow made to God, it was still more restrictive than the voluntary offering, which could even use a deformed animal (22:23).”

“be a vow: Lev 22:18-21, Lev 23:38; Num 15:3; Deu 12:6, Deu 12:11, Deu 12:17, Deu 12:26; Psa 66:13, Psa 116:14, Psa 116:18; Nah 1:15 a voluntary: Lev 22:23, Lev 22:29; Deu 12:6; Eze 46:12 also the: Lev 19:5-8 Leviticus 7:17”
