Lucius Caecilius Firmianus Lactantius

For the prophet does not speak this way: “And the Lord said to me,” but to Jesus [Joshua], in order to show that he was not speaking of himself but of Christ to whom God was then speaking. For that Jesus [Joshua] was a figure of Christ. Although he was first called Hoshea, Moses, foreseeing the future, ordered him to be called Joshua (or Jesus), so that, since he was selected leader of the soldiery against Amalek who was attacking the children of Israel, he might overcome the adversary through the figure of his name and lead the people into the land of promise. And for this reason also he succeeded Moses, to show that the new law given through Jesus Christ would succeed the old law which was given through Moses.

Also Moses himself: “In the last days the Lord God will circumcise your heart that you may love the Lord your God.” And in like manner in Jesus [Joshua], the son of Nun, the successor of Moses, we note: “And the Lord said to Jesus [Joshua]: Make for yourself knives of stone exceedingly sharp and sit and circumcise a second time the children of Israel.” He said that this second circumcision would not be of the flesh as was the first, which the Jews still practice, but of the heart and spirit, which Christ, who was the true Jesus, gave.
