'Contribution' in the Bible

Of this he shall present one of every offering as a contribution to the Lord; it shall belong to the priest who sprinkles the blood of the peace offerings.

You shall give the right thigh to the priest as a contribution from the sacrifices of your peace offerings.

For I have taken the breast of the wave offering and the thigh of the contribution from the sons of Israel from the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their due forever from the sons of Israel.
