The introduction in Deu 29:2 resembles that in Deu 5:1. “All Israel” is the nation in all its members (see Deu 29:10, Deu 29:11). - Israel had no doubt seen the mighty acts of the Lord in Egypt (Deu 29:2 and Deu 29:3; cf. Deu 4:34; Deu 7:19), but Jehovah had not given them a heart, i.e., understanding, to perceive, eyes to see, and ears to hear, until this day. With this complaint, Moses does not intend to excuse the previous want of susceptibility on the part of the nation to the manifestations of grace on the part of the Lord, but simply to explain the necessity for the repeated allusion to the gracious acts of God, and to urge the people to lay them truly to heart. “By reproving the dulness of the past, he would stimulate them to a desire to understand: just as if he had said, that for a long time they had been insensible to so many miracles, and therefore they ought not to delay any longer, but to arouse themselves to hearken better unto God” (Calvin). The Lord had not yet given the people an understanding heart, because the people had not yet asked for it, simply because the need of it was not felt (cf. Deu 4:26).
