Misinterpretations often treat this as a general promise of financial prosperity or mandatory tithing for modern Christians, overlooking its specific application to the Levitical priests under the Mosaic covenant; others literalize 'covenant of salt' as requiring salted offerings without grasping its symbolic meaning for perpetuity, or extend it to justify perpetual clergy privileges outside the old covenant framework, ignoring the New Testament shift to Christ's eternal priesthood.
Numbers 18:19
King James Version (1769)
19 All the heave offerings of the holy things, which the children of Israel offer unto the Lord, have I given thee, and thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the Lord unto thee and to thy seed with thee.
God affirms an eternal covenant with Aaron and his priestly descendants, granting them all the holy heave offerings given by Israel as their perpetual portion for service in the tabernacle. The 'covenant of salt' emphasizes its unbreakable and enduring nature, like salt's preservative power, ensuring divine provision and faithfulness to the priesthood that mediates between God and His people.
