Embrimaomai (ἐμβριμάομαι, G1690) means to be deeply moved in spirit, to groan inwardly with strong emotion, to snort with anger, to sternly charge or warn. From en (in) + brimē (strength, snorting of horses — sound of forceful breath). It appears in Matthew 9:30; Mark 1:43; 14:5; and most profoundly in John 11:33,38 — where Jesus encounters the grief at Lazarus' tomb.
John 11:33 says that when Jesus saw Mary weeping and the Jews weeping, 'he was deeply moved (enebrimēsato) in spirit and troubled.' And again in verse 38: 'Jesus, once more deeply moved, came to the tomb.' This is one of the most theologically important passages about the emotional life of Jesus. The word embrimaomai suggests something volcanic — not gentle sympathy but a forceful, almost angry grief. Many scholars see in it Jesus' rage against death itself — the cosmic intruder, the last enemy (1 Corinthians 15:26), the great defiler of God's good creation. Jesus doesn't merely mourn; He is roused to indignation at the power of death. This is why He raises Lazarus — not as a comfort performance but as an act of war against death. The resurrection of Lazarus is a preview of the resurrection of all, and both spring from Jesus' embrimaomai — His deep, furious, redeeming love.
