In Hosea 2:5 we find out that Gomer cheated on Hosea. According to the Law of Moses, Hosea could have her put to death! But God commanded him to do the opposite. In Hosea 3:2 it says that Hosea “bought her to me for fifteen pieces of silver.” Hosea paid to get his unfaithful wife back. . . a beautiful symbol of how Christ has bought us back despite how often we are unfaithful to Him!
