Sabbath, as the day of rest, was formally grounded in the account of God's resting after the work of creation (Gen. 2: 2); and the necessity of rest both for animals (Ezek. 34: 14) and people (2 Sam. 4: 5) was an established part of Hebrew life. In the NT the promise of God at the end of earthly life is named as rest (Heb. 4: 1; Rev. 14: 13). The idea is that the Sabbath rest not only commemorated the past work of God but also looked forward to the as yet unfinished work of Christ. The Hebrews failed to achieve the fulfilment of their covenant life (Exod. 33: 12–14) in fellowship with God. NT writers offer this promise to believers in Christ.
