Glory over me - See the margin, “have honor over me,” i. e. have the honor, or advantage over me, directing me when I shall entreat God for thee and thy servants.
When - Or by when; i. e. for what exact time. Pharaoh’s answer in Exodus 5:10 refers to this, by tomorrow. The shortness of the time would, of course, be a test of the supernatural character of the transaction.
