The wish is expressed that the Lord will send assistance, with the intent, of course, that the army will be victorious. This assistance can arrive in a natural or a miraculous way. Help is expected as coming from the holy place in Jerusalem. That is where David had placed the ark (2 Samuel 6:17). Therefore, the symbol of God’s presence is in Zion or Jerusalem. Let therefore the help come from Zion.
3 Que du sanctuaire il t'envoie du secours,Que de Sion il te soutienne!
