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, 17; 2 Kings
16:13; Joel 1:9, 13; 2:14), presented daily (Ex. 29:40), on the
Sabbath (Num. 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 (Num. 15:5; 28:7, 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.
