Psalm 90:3 depicts God turning man back to dust — directly echoing the 'returns to the earth' in Psalm 146:4.

Psalm 104:29 similarly describes God taking away breath and returning to dust, reinforcing the mortality theme.

Genesis 3:19 states 'to dust you shall return' — the same curse of mortality that Psalm 146:4 describes as breath departing.

Job 14:10 similarly asks about man breathing his last and perishing, illustrating the same mortality theme.

Job 14:21 notes that the dead are unaware of their children's fate — illustrating the perishing of plans in Psalm 146:4.

Job 17:11 says 'my plans are broken off' — the same end of human schemes that Psalm 146:4 describes.

In Job 27:3, breath is the spirit of God in man's nostrils — the same life that departs in Psalm 146:4, linking mortality to divine origin.

Ecclesiastes 12:7 adds that the spirit returns to God when dust returns to earth — fulfilling the death process in Psalm 146:4.

Isaiah 2:22 warns against trusting man whose breath is in his nostrils — because as Psalm 146:4 shows, that breath departs and plans perish.

Daniel 5:23 declares that God holds man's breath in His hand — reinforcing that the breath's departure in Psalm 146:4 is under God's control.

In Job 4:19, 'houses of clay' and 'foundation in dust' directly echo the return to earth — strong mortal frailty imagery.

In Job 12:10, God holds the breath of all — shows the source of the breath that departs in Psalm 146:4.

In Proverbs 11:7, the wicked's hope perishes at death — directly parallels the thought perishing here.

In Ecclesiastes 9:6, love, hate, and envy perish — all mental/emotional activity ceases, just like thoughts.

Genesis 2:7 describes God forming man from dust and breathing life — the reverse of the death process described here.

In Job 4:21, dying 'without wisdom' parallels the perishing of thoughts — both stress the end of human capacity at death.
