'Offerings' in the Bible

and did I choose him out of all the tribes of Israel to be my priest, to go up unto mine altar, to burn incense, to wear an ephod before me? and did I give unto the house of thy father all the offerings of the children of Israel made by fire?

Wherefore kick ye at my sacrifice and at mine offering, which I have commanded in my habitation, and honorest thy sons above me, to make yourselves fat with the chiefest of all the offerings of Israel my people?
