Read 1 Samuel 14
Saul makes an oath, that no-one can eat until the battle is over. Making oaths and promises that concern just one self is hard enough, it's actually impossible. Making an oath that concerns thousands is just stupid. This example comes up in several places in the bible, we're told to not make oaths or promises, simply to do our best and trust in God.
