Charles H. Spurgeon on Psalms 116:3

Gat hold upon me. The original word is, found me, as we put in the margin. They found him, as an officer or serjeant finds a person that he is sent to arrest; who no sooner finds him, but he takes hold of him, or takes him into custody. When warrants are sent out to take a man who keeps out of the way, the return is, Non est inventus, the man is not found, he cannot be met with, or taken hold of. David's pains quickly found him, and having found him they gat hold of him. Such finding is so certainly and suddenly followed With taking hold, and holding what is taken, that one word in the Hebrew serves to express both acts. When God sends out troubles and afflictions as officers to attack any man, they will find him, and finding him, they will take hold of him. The days of affliction will take hold; there's no striving, no struggling with them, no getting out of their hands. These divine pursuivants will neither be persuaded nor bribed to let you go, till God speak the word, till God say, Deliver him, release him. I found trouble and sorrow. I found trouble which I looked not for. I was not searching after sorrow, but I found it. There's an elegancy in the original. The Hebrew is, "The pains of hell found me." They found me, I did not find them; but no sooner had the pains of hell found me, than I found trouble and sorrow, enough, and soon enough. Joseph Caryl.
