'Altar' in the Bible

that I had chosen him out of all the tribes of Israel to be my priest, to offer up burnt offerings on my altar, burn incense, and carry the ephod in my presence? And did I not give to your ancestors' family all the Israeli fire-offerings?

Any of you whom I don't eliminate from serving at my altar will grow tired from weeping, and their souls will grieve. All the increase of your family will die by violence.

He would return to Ramah because his house was there, and judged Israel from there. He also built an altar to the LORD there.

Saul built an altar to the LORD; it was the first altar that he built to the LORD.
