Commentaire sur Isaïe 52:12

For the Lord goes before you to lead you on the way, and one whose agent advances before him to lead him on the way his departure is not in haste. And not in the flurry of flight shall you go, for your rear guard is the God of Israel. He will follow you to guard you from any pursuer. Comp. (Num. 10:25) “And the division of the camp of Dan shall travel, the rear guard of all the camps.” Whoever goes after the camp is called מְאַסֵּף, the rear guard, because he waits for the stragglers and the stumblers. Similarly, Scripture states in Joshua (6: 13): “And the rear guard was going after the Ark.”
