Forty years old [was] I when Moses the servant of the Lord
sent me from Kadeshbarnea to espy out the land
Not he alone, but eleven more with him, one out of every tribe; his age he mentions, and of which, or near it, it is highly probable the rest of the spies were, to show that he and they were in the prime of their days, both as to bodily strength and intellectual capacity, which were requisite for such service as to spy out the land, of what quality that and its inhabitants were; and Moses he calls the servant of the Lord, because it was by the order and appointment of God, signified to Moses, that this was done; and the place from whence they were sent forth is named, which ascertains what that Kadesh was, where Israel was encamped when the spies were sent, ( Numbers 13:26 ) ;
and I brought him word again, as [it was] in mine heart;
that is, he gave to Moses upon his return a sincere, honest and faithful representation of the land, and its inhabitants, as it appeared to him.
