Jeremiah 20:9 describes a burning fire in the heart that cannot be held in — the same internal pressure that drives the psalmist to speak.

Job 7:11 declares 'I will not restrain my mouth' — directly parallel to the psalmist's release of pent-up speech.

In Job 32:18, Elihu feels constrained by the spirit within him, similar to the fire that compels David to speak in Psalm 39:3.

Luke 24:32 records hearts burning while Jesus explains Scripture — a different cause but the same 'heart on fire' imagery.

Ezekiel 3:14 speaks of going in the heat of his spirit — a similar inner fire, though Ezekiel's is from the Spirit's leading.
