They that are mad against me are sworn against me - The Chaldeans are determined to destroy us; and they have bound themselves by oath to do it. See a similar case related Acts 23:12-14, where a number of Jews had bound themselves by an oath neither to eat nor drink till they had slain Paul.
Mine enemies reproach me all the day - Continually. They reproach me as one of thy people; or, I bear reproaches in common with others, and it becomes to me a personal matter, so entirely are my feelings and interests identified with those of thy people. Perhaps there were also, mingled with this, personal reproaches and calumnies.
And they that are mad against me - Angry; excited even to madness.
Are sworn against me - literally, “swear by me,” or against me. The meaning is, that they have conspired together under the solemnity of an oath to do me harm. It is not the wrath of an individual that I am to meet, but the combined wrath of those who act under the solemnities of an oath. Compare Acts 23:12.
