'Sacrificing' in the Bible

King Solomon and all the congregation of Israel, who had assembled before him, were with him before the ark, sacrificing sheep and oxen, so many that they could not be counted or numbered.

Jeroboam held a feast on the fifteenth day of the eighth month, like the feast which is kept in Judah, and he went up to the altar; he did this in Bethel, sacrificing to the calves which he had made. And he stationed in Bethel the priests of the high places which he had made.
