1 Samuel 6:4

Five golden emerods Figures in gold representing the disease. Five golden mice Images of the mice which had marred their land by destroying its fruits. According to the number of the lords of the Philistines Who were five, and were to be at the charge of offering one for each of them. These things they offered, not in contempt of God, for they sought to gain his favour hereby; but in testimony of their humiliation, that, by leaving this monument of their shame and misery, they might obtain pity from God. It may be observed here, that it appears to have been a custom among the ancient heathen, to consecrate unto their gods such monuments of their deliverances as represented the evils from which they were freed. So the Philistines did on this occasion. And, according to Tavernier, this is still practised among the Indians. When any pilgrim goes to a pagod for the cure of a disease, he brings the figure of the member affected; made either of gold, silver, or copper, according to his quality; which he offers to his god, and then falls a singing, as all others do after they have offered.
