'Offer Sacrifices' in the Bible

The king went to Gibeon to offer sacrifices, for it had the most prominent of the high places. Solomon would offer up a thousand burnt sacrifices on the altar there.

if this people go up to offer sacrifices in the house of Jehovah at Jerusalem, then will the heart of this people turn again unto their lord, even unto Rehoboam king of Judah; and they will kill me, and return to Rehoboam king of Judah.

On the fifteenth day of the eighth month (a date he had arbitrarily chosen) Jeroboam offered sacrifices on the altar he had made in Bethel. He inaugurated a festival for the Israelites and went up to the altar to offer sacrifices.

With the authority of the Lord he cried out against the altar, "O altar, altar! This is what the Lord says, 'Look, a son named Josiah will be born to the Davidic dynasty. He will sacrifice on you the priests of the high places who offer sacrifices on you. Human bones will be burned on you.'"

He followed in his father Asa's footsteps and was careful to do what the Lord approved. However, the high places were not eliminated; the people continued to offer sacrifices and burn incense on the high places.
