Exodus 10:12 And the Lord said unto Moses, Stretch out thine hand over the land of Egypt for the locusts, that they may come up upon the land of Egypt, and eat every herb of the land, even all that the hail hath left.
[Patriarchs & Prophets pp 270>271] The Lord was manifesting His power, to confirm the faith of Israel in Him as the only true and living God. He would give unmistakable evidence of the difference He placed between them and the Egyptians, and would cause all nations to know that the Hebrews, whom they had despised and oppressed, were under the protection of the God of heaven. Moses warned the monarch that if he still remained obstinate, a plague of locusts would be sent, which would cover the face of the earth and eat up every green thing that remained.
They would fill the houses, even the palace itself; such a scourge, he said, as “neither thy fathers, nor thy fathers’ fathers have seen, since the day that they were upon the earth unto this day.” The counselors of Pharaoh stood aghast. The nation had sustained great loss in the death of their cattle. Many of the people had been killed by the hail. The forests were broken down and the crops destroyed. They were fast losing all that had been gained by the labor of the Hebrews. The whole land was threatened with starvation.
Princes and courtiers pressed about the king and angrily demanded, “How long shall this man be a snare unto us? Let the men go, that they may serve the Lord their God: knowest thou not yet that Egypt is destroyed?” Moses and Aaron were again summoned, and the monarch said to them, “Go, serve the Lord your God: but who are they that shall go?” The answer was, “We will go with our young and with our old, with our sons and with our daughters, with our flocks and with our herds will we go; for we must hold a feast unto the Lord.”
Exodus 10:19 And the Lord turned a mighty strong west wind, which took away the locusts, and cast them into the Red sea; there remained not one locust in all the coasts of Egypt. 20 But the Lord hardened Pharaoh's heart, so that he would not let the children of Israel go.
May God add His blessing to the study of His word. “Good night” and God bless!
