The Hebrew noun shebuah means an oath, a solemn vow, or a sworn pledge. It derives from the root shaba (to swear, to seven oneself), with the numeral seven (sheva) embedded in the concept of a binding covenant oath.
Shebuah is the language of covenant commitment. God swore oaths to Abraham (Genesis 26:3), to David (Psalm 89:3), and to Israel. His oaths are unconditional guarantees of His faithfulness. Human oaths invoke God's name and carry the weight of accountability before Him. Jesus addressed the abuse of oaths in Matthew 5:33-37 while affirming their seriousness. The very name 'Beersheba' (Beer-sheba) means 'well of the oath,' marking a place where covenants were sealed.
