TSK · Exodus 9:3

And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days' journey into the wilderness, and sacrifice unto Jehovah our God, lest he fall upon us with pestilence, or with the sword.

And see; if it goeth up by the way of its own border to Beth-shemesh, then he hath done us this great evil: but if not, then we shall know that it is not his hand that smote us; it was a chance that happened to us.

And now, behold, the hand of the Lord is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell on him a mist and a darkness; and he went about seeking some to lead him by the hand.
