Numbers 28:7 - Ellicott's Commentary On The Whole Bible

Shalt thou cause the strong wine to be poured... — Better, pour out the drink offering of strong drink. The word shecar, which is here rendered “strong wine,” denotes any kind of intoxicating drink, whether made from grapes, honey, or grain; but it is more frequently used to denote a drink which is not made from grapes, as, e.g., in Leviticus 10:9, where the command is given to Aaron and his sons not to drink “wine nor strong drink” (shecar) when they went into the tent of meeting. In the parallel passage in Exodus, the drink offering was to consist of “the fourth part of an hin of wine” (Numbers 29:40). (Comp. Numbers 15:5.) In Exodus 30:9 it is forbidden to pour any drink offering upon the altar of incense, from which passage it has been inferred that the drink offerings were poured upon the altar of burnt sacrifice.
