What is Isaiah 8 and Psalms 107:1

Isaiah’s testimonies 1The LORD said to me, “Take a large tablet, and write on it in ordinary letters, For Maher-shalal-hash-baz. 2Summon trusted people, Uriah the priest and Zechariah, Jeberechiah’s son, to witness it.” 3I then had sex with the prophetess, and she became pregnant and gave birth to a son. Then the LORD said to me, “Name him Maher-shalal-hash-baz. 4Before the boy knows how to say ‘my father’ and ‘my mother,’ the wealth of Damascus and the spoil of Samaria will be carried away before the king of Assyria.” 5The LORD spoke again to me: 6Since this people has rejected the waters of Shiloah that flow gently, and instead rejoices over Rezin and Remaliah’s son— 7therefore, look, the Lord is raising up against them the powerful floodwaters of the Euphrates, the king of Assyria and all his glory. It will rise up over all its channels, overflowing all its banks, 8and sweep into Judah, flooding, overflowing, and reaching up to the neck. But God is with us; the span of his wings will cover the width of the land. 9Unite yourselves, peoples, and be shattered! Listen, all distant places of the earth! Prepare to be shattered! Prepare to be shattered! 10Create a plan, but be frustrated! Speak a word, but it won’t stand, for God is with us. 11The LORD spoke to me, taking hold of me and warning me not to walk in the way of this people: 12Don’t call conspiracy all that this people calls conspiracy. Don’t fear what they fear, and don’t be terrified. 13It is the LORD of heavenly forces whom you should hold sacred, whom you should fear, and whom you should hold in awe. 14God will become a sanctuary— but he will be a stone to trip over and a rock to stumble on for the two houses of Israel; a trap and a snare for those living in Jerusalem. 15Many of them will stumble and fall, and be broken, snared, and captured. 16Bind up the testimony; seal up the teaching among my disciples. 17I will wait for the LORD, who has hidden his face from the house of Jacob, and I will hope in God. 18Look! I and the children the LORD gave me are signs and wonders in Israel from the LORD of heavenly forces, who lives on Mount Zion. 19If they say to you: “Consult the ghosts and the spirits that chirp and mutter. (Shouldn’t a people consult its gods?) Consult the dead on behalf of the living 20for instruction and for testimony”—they will surely say such things, but they will never see the dawn. 21They will pass through the land, dejected and hungry, and when they are hungry, they will be enraged and will curse their king and God. They will turn toward heaven 22and look to the earth, but they will see only distress and darkness, random movement, and the anguish and doom of banishment. “Give thanks to the LORD because he is good, because his faithful love lasts forever!” https://temtube.com/
