'Gift' in the Bible

So then, if you bring your gift to the altar and there remember that your brother has something against you,

leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift.

so that your gift may be in secret. And your Father, who sees in secret, will reward you.

And, 'Whoever swears by the altar is bound by nothing. But if anyone swears by the gift on it he is bound by the oath.'

You are blind! For which is greater, the gift or the altar that makes the gift sacred?
