Footnote
a Asher Goldenberg writes in Metre and Its Significance in the Bible (Hebrew) that in the First Temple period, proper names were commonly given a longer form, incorporating part of the Tetragrammaton, to indicate loyalty to Jehovah. He comments that “in the Pentateuch, Moses changes the name of Hoshe ben-Nun into ‘Jehoshua’ when he sends him to go spying; thus he foresaw that [Joshua] would not betray [Jehovah].”
