YLT(i)
28 And Moses saith, `By this ye do know that Jehovah hath sent me to do all these works, that they are not from my own heart;
29 if according to the death of all men these die—or the charge of all men is charged upon them—Jehovah hath not sent me;
30 and if a strange thing Jehovah do, and the ground hath opened her mouth and swallowed them, and all that they have, and they have gone down alive to Sheol—then ye have known that these men have despised Jehovah.'
