But if my father intends to bring evil on you, then may the LORD punish me, and ever so severely, if I do not tell you and send you on your way in safety. May the LORD be with you, just as He has been with my father.
KJV
The LORD do so and much more to Jonathan: but if it please my father [to do] thee evil, then I will shew it thee, and send thee away, that thou mayest go in peace: and the LORD be with thee, as he hath been with my father.
ASV
Jehovah do so to Jonathan, and more also, should it please my father to do thee evil, if I disclose it not unto thee, and send thee away, that thou mayest go in peace: and Jehovah be with thee, as he hath been with my father.
