No explicit mention of queens is made till we read of the “queen of Sheba.” The wives of the kings of Israel are not so designated. In Psalms 45:9, the Hebrew for “queen” is not malkah, one actually ruling like the Queen of Sheba, but shegal, which simply means the king's wife.
In 1 Kings 11:19, Pharaoh's wife is called “the queen,” but the Hebrew word so rendered (g'birah is simply a title of honor, denoting a royal lady, used sometimes for “queen-mother” (1 Kings 15:13; 2 Chron. 15:16). In Song of Songs 6:8, 9, the king's wives are styled “queens” (Hebrew: melakhoth).
