Malachi 2:5

The Lord’s covenant with Levi was a covenant of grant. In this type of covenant one individual, and perhaps his descendants, received a promise of continuing blessing for a special service rendered. The special service that Levi and his descendants rendered to God involved serving as His priests. The covenant that God made with Levi and his descendants resulted in life and peace for them. God gave them these blessings because they respected Yahweh and feared His name (Numbers 18:7-8; Numbers 18:19-21; cf. Numbers 25:10-13).
