Saul said nothing that day, for he thought, "Something must have happened to David to make him ceremonially unclean – surely he is unclean." (NIV)
Yet Saul said nothing that day, for he thought, Something has befallen him and he is not clean--surely he is not clean. (AMP)
Nevertheless Saul spake not any thing that day: for he thought, Something hath befallen him, he is not clean; surely he is not clean. (KJV)
