Adam Clarke, on Lam 3:13

“He. He hath shot into my reins the daughters of his quiver.”

“The arrows of his quiver - בני אשפתו beney ashpatho, "The sons of his quiver." The issue or effect; the subject, adjunct, or accident, or produce of a thing, is frequently denominated its son or child. So arrows that issue from a quiver are here termed the sons of the quiver.”
