Genesis 21:20

רבה קשת AN ARCHER — One who shoots arrows by a bow. (This is the explanation of רבה קַשָּׁת he is so designated after his occupation, that of a bow-man — just as חַמָּר denotes one who is an ass driver, גַּמָּל a camel driver, צַיָּד a huntsman; consequently the ש has a Dagesh (which distinguishes all these forms). — He used to live in the wilderness and rob travelers. It is to this the statement refers, (15:12) ידו בכל “his hand shall be against everyone, etc.”

וַיְהִ֧י אֱלֹהִ֛ים אֶת־הַנַּ֖עַר וַיִּגְדָּ֑ל וַיֵּ֙שֶׁב֙ בַּמִּדְבָּ֔ר וַיְהִ֖י רֹבֶ֥ה קַשָּֽׁת׃

And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer.
