Ezekiel 27:11

The men of Arvad with thine army were upon thy walls round about, and the Gammadims were in thy towers: they hanged their shields upon thy walls round about; they have made thy beauty perfect.

The Gammadims were in thy towers - rather, as the Tyrians were Syro-Phoenicians, from a Syriac root meaning daring, 'men of daring' (Ludovicus de Dieu). There was probably a root [gaamad], daring, akin to the Syriac. It is not likely the keeping of watch "in the towers" would have been entrusted to foreigners. Others take it from a Hebrew root, 'a danger,' or short sword such as Ehud used, with two edges and of a cubit length, in killing Eglon (Judges 3:16), 'short-swordsmen.' Thus, the name comes from [ gomed (H1574)] a cubit: or, in the former interpretation, an arm, 'men powerful in arm.'
