'Altar' in the Bible

So if you are offering your gift on the altar, and there you remember that your brother has something against you,

leave your gift there in front of the altar. First go and be reconciled with your brother, and then come and offer your gift.

Also, ‘Whoever takes an oath by the altar, it means nothing. But whoever takes an oath by the gift that is on it is bound by his oath.’

Blind people! For which is greater, the gift or the altar that sanctifies the gift?

Therefore, the one who takes an oath by the altar takes an oath by it and by everything on it.

So all the righteous blood shed on the earth will be charged to you, from the blood of righteous Abel to the blood of Zechariah, son of Berechiah, whom you murdered between the sanctuary and the altar.
