Jeremiah 32:17 - Matthew Poole's English Annotations on the Holy Bible

He beginneth his prayer with a recognition of God's omnipotency, and the infiniteness of his power, which was showed in his first making the heaven and the earth, as we read, Genesis 1:1 Psalms 146:6. God himself used this instance to confirm his people's faith in his ability to do what he pleased, Jeremiah 27:5. It is observable, that the servants of God in holy writ used in their prayers to give God such names as might help to confirm their faith as to what they asked. Nothing can further be necessary to confirm our faith that we shall have what we ask, than for us to be persuaded that the person is able to do it, and also willing. The prophet beginneth with a declaration of his faith in God as to the first, then goes on to the second.
