But among these there was not a man of them {g} whom Moses and Aaron the priest numbered, when they numbered the children of Israel in the wilderness of Sinai.

(g) In which appears the great power of God, that so wonderfully increased his people.

Jamieson-Fausset-Brown Bible Commentary

64. among these there was not a man . numbered . in the wilderness of Sinai-The statement in this verse must not be considered absolute. For, besides Caleb and Joshua, there were alive at this time Eleazar and Ithamar, and in all probability a considerable number of Levites, who had no participation in the popular defections in the wilderness. The tribe of Levi, having neither sent a spy into Canaan, nor being included in the enumeration at Sinai, must be regarded as not coming within the range of the fatal sentence; and therefore it would exhibit a spectacle not to be witnessed in the other tribes of many in their ranks above sixty years of age.

Matthew Henry's Concise Commentary

26:63-65 The execution of the sentence passed on the murmurers, chap. 14:29, is observable. There was not one man numbered now, who was numbered then, but Caleb and Joshua. Here appeared the righteousness of God, and his faithfulness to his threatenings. Especially observe the truth of God, in performing his promise to Caleb and Joshua. Death makes awful havoc of the human species, and causes surprising changes in families and nations; yet all is appointed in perfect wisdom, justice, and truth, by the Lord himself. This should stir us up to think upon the hateful nature of sin, the cause of all these devastations. We should renew our repentance, seek forgiveness, value the salvation of Christ, remember how frail we are, prepare for the summons of death, and fill up our days in serving our generation according to the will of God.
