BSB(i)
28 Then Moses said, “This is how you will know that the LORD has sent me to do all these things, for it was not my own doing:
29 If these men die a natural death, or if they suffer the fate of all men, then the LORD has not sent me.
30 But if the LORD brings about something unprecedented, and the earth opens its mouth and swallows them and all that belongs to them so that they go down alive into Sheol, then you will know that these men have treated the LORD with contempt.”
