drink-offering
consisted of wine (Numbers 15:5; Hos. 9:4) poured around the altar (Exodus 30:9)
Joined with meat-offerings (Numbers 6:15, 17; 2 Kings 16:13; Joel 1:9, 13; 2:14), presented daily (Exodus 29:40), on the Sabbath (Numbers 28:9), and on feast-days (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 (Numbers 15:5; 28:7, 14).
“Drink offerings of blood” (Psalm 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.
