Charles Ellicott Commentary Isaiah 21:3

"Therefore are my loins filled with anguish; pangs have taken hold upon me, as the pangs of a woman in travail: I am pained so that I cannot hear; I am dismayed so that I cannot see." — Isaiah 21:3 (ASV)

Therefore are my loins filled with pain ... —Compare to Nahum 2:10; Ezekiel 21:6; and for the image of the “woman in travail,”Isaiah 13:8; Jeremiah 30:6. The vision of destruction is so terrible that it overpowers all feeling of exultation, and oppresses the prophet like a horrible nightmare.
