In 1 Samuel 14:24-52 Saul, like Jephthah before him, makes a rash oath. God’s people must be careful about the kind of oaths they take. In today’s world oaths and vows are treated as things that are insignificant, things that can be broken on a whim. The Scriptures, however, teach that you must uphold every lawful oath and that every unlawful oath is sin.
