What is Isaiah 21 and Hebrews 10:23

The Fall of Babylonia 1This is a message about a desert beside the sea: Enemies from a hostile nation attack like a whirlwind from the Southern Desert. 2What a horrible vision was shown to me— a vision of betrayal and destruction. Tell Elam and Media to surround and attack the Babylonians. The Lord has sworn to end the suffering they caused. 3I’m in terrible pain like a woman giving birth. I’m shocked and hurt so much that I can’t hear or see. 4My head spins; I’m horrified! Early evening, my favorite time, has become a nightmare. 5In Babylon the high officials were having a feast. They were eating and drinking, when someone shouted, “Officers, take your places! Grab your shields.” 6The Lord said to me, “Send guards to find out what’s going on. 7When they see cavalry troops and columns of soldiers on donkeys and camels, tell them to be ready!” 8Then a guard said, “I have stood day and night on this watchtower, Lord. 9 Now I see column after column of cavalry troops.” At once someone shouted, “Babylon has fallen! Every idol in the city lies broken on the ground.” 10Then I said, “My people, you have suffered terribly, but I have a message for you from the Lord All-Powerful, the God of Israel.” How Much Longer? 11This is a message about Dumah: From the country of Seir, someone shouts to me, “Guard, how much longer before daylight?” 12From my guard post, I answered, “Morning will soon be here, but night will return. If you want to know more, come back later.” 13This is a message for Arabs who live in the barren desert in the region of Dedan: You must order your caravans 14to bring water for those who are thirsty. You people of Tema must bring food for the hungry refugees. 15They are worn out and weary from being chased by enemies with swords and arrows. 16The Lord said to me: A year from now the glory of the people of Kedar will all come to an end, just as a worker’s contract ends after a year. 17Only a few of their warriors will be left with bows and arrows. This is a promise that I, the Lord God of Israel, have made. Let us hold fast the confession of our hope without wavering, for he who promised is faithful. https://temtube.com/
