Deuteronomy 1:9 - Joseph Benson’s Commentary on the Old and New Testaments

I spake unto you Unto your fathers, who were alive at the time here referred to, but now dead, Numbers 26:64. At that time That is, about that time, a little before their coming to Horeb. See Exodus 18. This was by the advice of Jethro, his father-in-law.
