'Rub' in the Bible

Men were assigned to take the prisoners and find clothes among the plunder for those who were naked. So they clothed them, supplied them with sandals, gave them food and drink, and provided them with oil to rub on their skin. They put the ones who couldn't walk on donkeys. They brought them back to their brothers at Jericho, the city of the date palm trees, and then returned to Samaria.
