David's Oath refers to the solemn promises and commitments made by David, the second king of Israel, as recorded in the Old Testament. These oaths are significant in understanding David's character, his relationship with God, and his interactions with others. They reflect his deep sense of duty, loyalty, and reverence for God's will.

Oath to Jonathan:

One of the most notable oaths made by David was to Jonathan, the son of King Saul. Despite Saul's animosity towards David, Jonathan and David shared a profound friendship. In 1 Samuel 20:16-17, Jonathan made a covenant with the house of David, saying, "So Jonathan made a covenant with the house of David, saying, 'May the LORD hold David’s enemies accountable.' And Jonathan had David reaffirm his vow out of love for him, for Jonathan loved David as he loved himself" . This oath was a mutual promise of loyalty and protection, transcending familial and political tensions.

Oath Concerning Saul's Descendants:

David also made an oath concerning the descendants of Saul. After Saul's death, David sought to honor his promise to Jonathan by showing kindness to Jonathan's son, Mephibosheth. In 2 Samuel 9:7, David said to Mephibosheth, "Do not be afraid, for I will surely show you kindness for the sake of your father Jonathan. I will restore to you all the land of your grandfather Saul, and you will always eat at my table" . This oath demonstrated David's commitment to his covenant with Jonathan and his respect for Saul's lineage.

Oath to Bathsheba:

David made a significant oath to Bathsheba, the mother of Solomon, regarding the succession of the throne. In 1 Kings 1:29-30, David swore, "As surely as the LORD lives, who has redeemed my life from all distress, I will surely carry out today what I swore to you by the LORD, the God of Israel: Solomon your son shall be king after me, and he shall sit on my throne in my place" . This oath was crucial in establishing Solomon as David's successor, ensuring the continuation of the Davidic line as ordained by God.

Oath to the LORD:

David's oaths were not limited to interpersonal relationships; he also made solemn vows to the LORD. In Psalm 132:2-5, David's commitment to building a house for the LORD is recorded: "He swore an oath to the LORD, he made a vow to the Mighty One of Jacob: 'I will not enter my house or get into my bed, I will not give sleep to my eyes or slumber to my eyelids, until I find a place for the LORD, a dwelling for the Mighty One of Jacob'" . This oath reflects David's deep desire to honor God and establish a permanent place of worship for the Israelites.

Significance:

David's oaths are integral to understanding his life and reign as king. They reveal his integrity, his dedication to God's purposes, and his unwavering loyalty to those he loved. These oaths also highlight the importance of covenantal relationships in the biblical narrative, underscoring themes of faithfulness, divine promise, and the unfolding of God's plan through human history.
