King James Version
“And turn ye not aside: for after vain which cannot profit nor deliver; for they vain.”
Context
18So Samuel called unto the LORD; and the LORD sent thunder and rain that day: and all the people greatly feared the LORD and Samuel.
19And all the people said unto Samuel, Pray for thy servants unto the LORD thy God, that we die not: for we have added unto all our sins evil, to ask us a king.
20And Samuel said unto the people, Fear not: ye have done all this wickedness: yet turn not aside from following the LORD, but serve the LORD with all your heart;
21And turn ye not aside: for after vain which cannot profit nor deliver; for they vain.
22For the LORD will not forsake his people for his great name’s sake: because it hath pleased the LORD to make you his people.
23Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you: but I will teach you the good and the right way:
24Only fear the LORD, and serve him in truth with all your heart: for consider how great he hath done for you.
