'Offering' 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 offering there before the altar and go; first be reconciled to your brother, and then come and present your offering.

And Jesus *said to him, “See that you tell no one; but go, show yourself to the priest and present the offering that Moses commanded, as a testimony to them.”

but ye say, Whoever may say to father or mother, An offering is whatever thou mayest be profited by me; --

And, ‘Whoever swears by the altar, that is nothing, but whoever swears by the offering on it, he is obligated.’

You blind men, which is more important, the offering, or the altar that sanctifies the offering?

so that on you will come the guilt of all the blood of the righteous shed on earth, from the blood of righteous Abel to the blood of Zechariah [the priest], the son of Berechiah, whom you murdered between the temple and the altar.
