What is Isaiah 18 and Isaiah 40:31

Ethiopia Will Be Punished 1 Downstream from Ethiopia lies the country of Egypt, swarming with insects. 2Egypt sends messengers up the Nile River on ships made of reeds. Send them fast to Ethiopia, whose people are tall and have smooth skin. Their land is divided by rivers; they are strong and brutal, feared all over the world. 3Everyone on this earth, listen with care! A signal will be given on the mountains, and you will hear a trumpet. 4The Lord said to me, “I will calmly look down from my home above— as calmly as the sun at noon or clouds in the heat of harvest season.” 5Before the blossoms can turn into grapes, God will cut off the sprouts and hack off the branches. 6Ethiopians will be food for mountain vultures during the summer and for wild animals during the winter. 7Those Ethiopians are tall and their skin is smooth. They are feared all over the world, because they are strong and brutal. But at that time they will come from their land divided by rivers, and they will bring gifts to the Lord All-Powerful, who is worshiped on Mount Zion. But those who trust in the LORD will find new strength. They will soar high on wings like eagles. They will run and not grow weary. They will walk and not faint. https://temtube.com/
