2 Kings 5:17

Two mules' burden of earth Wherewith I may make an altar of earth, as was usual, Exodus 20:24. He desires the earth of this land, because he thought it more holy and acceptable to God, and proper for his service; or because he would, by this token, profess and declare his conjunction with the Israelites in the worship of God, and constantly put himself in mind of his great obligation to that God, from whose land this was taken: and though he might freely have taken this earth without asking any leave, yet he rather desires it from the prophet's gift, as believing that he, who had put so great a virtue into the waters of Israel, could put as much into the earth of Israel, and make it as useful and beneficial to him in a better way. And these thoughts, though extravagant and groundless, yet were excusable in a heathen and a novice, who was not yet thoroughly instructed in true religion.
