'Offer' in the Bible

Then the cities of Judah and the people of Jerusalem will go and cry to the [man-made] gods to whom they burn incense, but they cannot save them in the time of their disaster.

Though they fast, I will not hear their cry; and though they offer burnt offerings and grain offerings, I will not accept them [because they are done as obligations, and not as acts of loving obedience]. Instead I will consume them by the sword, by famine, and by pestilence.”

and the Levitical priests shall never lack a man (descendant) to offer burnt offerings before Me and to burn grain offerings and to prepare sacrifices all day long.’”
