Charles Ellicott Commentary Jeremiah 12:7

"I have forsaken my house, I have cast off my heritage; I have given the dearly beloved of my soul into the hand of her enemies." — Jeremiah 12:7 (ASV)

I have forsaken my house. —The speaker is clearly Jehovah, but the connection with what precedes is not clear. Possibly, this chapter contains what might be called fragmentary pieces in a poet's writings—composed at intervals, reflecting different phases of thought, and later arranged without the headings, titles, and spacing that modern bookmaking has made familiar. So far as a sequence of thought is traceable, it is this: “You complain of your own sufferings, but there are worse things yet in store for you; and what after all are yours, compared with those that I, Jehovah, have brought upon my heritage, dear as it is to me?”

I have left. —Better, I have cast away.

Into the hand. —Literally, the palm, as given over utterly, unable to resist, and not needing the “grasp” of the whole hand.
