'Heart Is Troubled' in the Bible

My soul, my soul! I am pained to my inmost heart; my heart is troubled in me; I am not able to be quiet, because the sound of the horn, the note of war, has come to my ears.

Is Ephraim my dear son? is he the child of my delight? for whenever I say things against him, I still keep him in my memory: so my heart is troubled for him; I will certainly have mercy on him, says the Lord.
