Charles Ellicott Commentary Numbers 28:2

"Command the children of Israel, and say unto them, My oblation, my food for my offerings made by fire, of a sweet savor unto me, shall ye observe to offer unto me in their due season." — Numbers 28:2 (ASV)

My offering, and my bread ... — Better, My oblation (even) my bread, etc. The offering, though presented by the hands of men, was God’s, not theirs. The silver is mine, and the gold is mine, saith the Lord of hosts (Haggai 2:8). Every beast of the forest is mine, and the cattle upon a thousand hills (Psalms 1:10). The word korban is a general term for an oblation.

It may denote in this place the minchah, or meal offering, or the shew-bread, offerings which were directly connected with a settled life in Canaan rather than with a nomadic life in the wilderness. Or the word lehem (bread) may be used to denote food generally, the sacrificial offerings being symbolically regarded as the Lord’s food. (Leviticus 3:16, where the same word is rendered food, and where the reference is to a portion of the flesh of the lamb and of the goat of the peace offering. See also Malachi 3:7.)
