Quotation zu Hoschea 14:9

9 (Numb. 13:16, cont.) “Then Moses called Hoshea (hwsh') ben Nun, Joshua (yhwsh')”: What reason did Moses see for adding a yod (i.e., a y) to Joshua's name?⁹ Cf. Sanh. 107a; Gen. R. 47:1; Exod. R. 6:1. It is simply that Caleb had taken his reward from the land, as stated (in Deut. 1:36)), “to him will I gave the land on which he has trod.” But Joshua [received] the reward [that would have gone to the other] ten [spies], in that a yod [which stands for] ten was added to his name. (Numb. 13:16, cont.) “Then Moses called Hoshea (hwsh') ben Nun, Joshua (yhwsh'). Another interpretation: When Moses saw that they were so very wicked, Moses said to him, “May the Lord (abbreviated to yh) save (ywshy') you from this evil generation.”
