Therefore you shall make images of your tumors, and images of your mice that mar the land; and you shall give glory to the God of Israel: peradventure he will lighten his hand from off you, and from off your gods, and from off your land.
"Ancient religious protocol mandated that the worshiper not approach his god(s) empty-handed (cf. Exodus 23:15; Deuteronomy 16:16)." [Note: Youngblood, p. 604.]
