Drink-offering
Consisted of wine (Num 15:5; Hos 9:4) poured around the altar (Ex 30:9). Joined with meat-offerings (Num 6:15, Num 6:17; 2 Kgs 16:13; Joel 1:9, Joel 1:13; Joel 2:14), presented daily (Ex 29:40), on the Sabbath (Num 28:9), and on feast-days (Num 28:14). One-fourth of an hin of wine was required for one lamb, one-third for a ram, and one-half for a bullock (Num 15:5; Num 28:7, Num 28:14). “Drink offerings of blood” (Ps 16:4) is used in allusion to the heathen practice of mingling the blood of animals sacrificed with wine or water, and pouring out the mixture in the worship of the gods, and the idea conveyed is that the psalmist would not partake of the abominations of the heathen.
