Save, LORD: let the king hear us when we call. Save, Lord - This verse was spoken by all the congregation, and was the chorus and conclusion of the piece.
The verse may be read, Lord, save the king! He will hear as in the day of our calling. The Vulgate, Septuagint, Ethiopic, Arabic, Anglo-Saxon, read the verse thus: Lord, save the king! and hear us whensoever we shall call upon thee. The Syriac reads differently: The Lord will save us: and our king will hear us in the day in which we shall call upon him. This refers all to God: while the others refer the latter clause to David. Lord, save David; and David will save us. "If thou preservest him, he will be thy minister for good to us." This appears to be the easiest sense of the place, and harmonizes with all the rest.
