Hide not thy face; which I in obedience to thy command am now seeking. Put not thy servant away, to wit, from thy face or presence, or from the place of thy worship, from which he either now was or formerly had been driven. Two ways God and he might be parted; either by God's departure or withdrawing from him, which he might do even in the place of his worship; or by God's putting him away from his presence. Against the first he seems to direct his prayer in the first clause, and against the latter in this.
