Exodus 10:21

Exo 10:21 And the LORD said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness [which] may be felt.

Ver. 21. Stretch out thine hand. ] Here was no warning. See Exodus 8:16 . As good, the more unexpected, is the more welcome; so evil, the more sudden, the more terrible.
