1 Samuel 18:3 shows this love resulting in a covenant — the immediate narrative consequence of the bond described.

In 1 Samuel 19:2, Jonathan warns David of Saul's murder plot, demonstrating the loyal love and protection that began with the covenant bond in 18:1.

In 1 Samuel 20:17, Jonathan renews the covenant love using the same phrase — 'loved him as his own life' — directly reinforcing the bond described in 18:1.

In 1 Samuel 31:2, Jonathan is killed in battle — the tragic end of the deep friendship begun in 18:1, showing its ultimate cost.

Genesis 44:30 uses identical language: 'his life is bound up with the boy's life' — a parallel expression of deep attachment.

Deuteronomy 13:6 uses the same Hebrew phrase 'as your own soul' to warn against a close friend leading astray, contrasting with Jonathan's faithful loyalty.

In 2 Samuel 1:26, David's lament echoes the depth of Jonathan's love from 18:1, calling it 'surpassing the love of women' — a retrospective tribute.

In 2 Samuel 9:1, David later seeks out Jonathan's descendant to show kindness, fulfilling the covenant bond formed here.

Proverbs 18:24 says a true friend sticks closer than a brother — Jonathan exemplifies this, as his covenant loyalty to David surpasses blood ties.
