The Onomasticon of the Spies
The list of the names of the spies sent out by Moshe in BaMidbar 13 stands out among the onomasticons (a fancy word for a list of names- so fancy , in fact, that you can't even spell check it) of the Torah. There are other name lists in BaMidbar -chapter 2,7 and 26. What make chapter 13 stand out is the large number of names in which it appears that the theophoric element has been dropped. A theophoric element is the name of God part of the name . An example would be Yechezkel which means God (El) will strengthen (me). The names in chapter 2 and 7 use the theophoric element El and Shaddai and possibly Tzur.
There are names in chapter 13 which seem to be truncated. Names like Sodi, Susi and Gamli seem to be missing a part of their name that refers to God. We are familiar with the name Gamliel. It would mean something like God (El) has rewarded (me). Although it cannot be proven it seems likely from other namelists that these type of names ending with a yod are incomplete names. (The names of the clans in BaMidbar 46 end in yod , but these are inflectional suffixes.)
So the question is why does the Torah cut off the names. What kind of name of God was removed. If it was a name like Baal which would imply avoda zarah (idol worship) , that would be a possible reason to remove those theophoric elements. But what would a baal suffix be doing in an Israelite name in the generation that left Egypt. There are two possibilities. We know that Baal, for instance, was worshiped in Egypt , probably by the Asiatic (Canaanite) population that lived in Egypt in the late Bronze age ( 1500 -1200 BCE). But more likely the term baal which literally means master at the time of the Canaanite conquest could have applied to the God of Israel. It was only later in the ninth through seventh centuries that the term took on a strictly idolatrous connotation. The Torah in anticipation then left out the part of the names that would be associated with idol worship.
Flying in the face of the second possibility is the results Of Jeffrey Tigays work on the onomasticon of Israel. Although his study ecompassed mostly names found in inscriptions from the eighth to the sixth century BCE, he found that over 90 percent of the names that had theophoric elements related to the Tetragrammaton- the four letter name of God . Examples are names like Yeshayahu (Isaiah) and Chizkiyahu (Hezekiah). It is possible that names in the tenth to the eighth century may have had a different result. Future inscriptional finds may shed more light on the question.
