Psalm 8:4 asks the exact same question, nearly word-for-word, about why God cares for mortals.

Psalm 146:3 warns not to trust mortals, reinforcing the frailty theme—why God would care for such creatures.

Psalm 146:4 continues by noting mortals return to dust and their plans vanish—underline human transience.

Job 7:17 poses a very similar rhetorical question about human insignificance before God’s attention.

Job 15:14 asks what mortals are, though it pivots to purity—still the same rhetorical form about human lowliness.

Hebrews 2:6 directly quotes Psalm 8:4, which is identical to this verse—a clear NT citation of the OT passage.

In 1 Chronicles 17:16, David echoes this same humility: 'Who am I, Lord God, that you have brought me this far?' — paralleling the wonder that God cares for insignificant humans.

Isaiah 2:22 warns against trusting mere humans, whose breath is fleeting — a different take on the same frailty noted here.

Genesis 18:27 has Abraham calling himself dust and ashes, a humble self-assessment similar to the lowliness implied here.

Job 14:3 asks if God fixes his eye on such a frail creature, similar wondering but with a tone of complaint about being judged.
