In these passages, Jehovah is called Redeemer and Savior; and since the Lord alone is Redeemer and Savior, it is he who is meant by “Jehovah.”
We can also see that the Lord is Jehovah—that is, that Jehovah is the Lord—from the following passages.
A shoot [will go forth] from the trunk of Jesse, and a sprout from its roots will bear fruit. The spirit of Jehovah will rest upon him. (Isaiah 11:1, 2)
It will be said on that day, “Behold, this is our God; we have waited for him to set us free. [This is] Jehovah; we have waited for him. Let us rejoice and be glad in his salvation.” (Isaiah 25:9)
A voice of someone in the wilderness crying out, “Prepare a pathway for Jehovah; make level in the desert a highway for our God.” The glory of Jehovah will be revealed, and all flesh will see it. Behold, the Lord Jehovih is coming in strength, and his arm will rule for him. (Isaiah 40:3, 5, 10)
I am Jehovah. I will make you a covenant for the people, a light for the nations. I am Jehovah. This is my name, and I will not give my glory to another. (Isaiah 42:6, 7, 8)
Behold, the days [are coming] when I will raise up for David a righteous branch who will rule as king, and prosper, and bring about judgment and justice on earth. And this is his name: they will call him “Jehovah our Righteousness.” (Jeremiah 23:5, 6; 33:15, 16)
As for you, Bethlehem Ephrata, one will come forth from you for me who will become the ruler in Israel. He will stand firm and feed [his flock] in the strength of Jehovah. (Micah 5:2, 4)
A Child has been born to us; a Son has been given to us. Leadership is upon his shoulder; and his name will be called God, Hero, Father of Eternity, on the throne of David, to establish and found it in judgment and in justice, from now on, even to eternity. (Isaiah 9:6, 7)
Jehovah will go forth and fight against the nations, and his feet will stand on the Mount of Olives, which faces Jerusalem. (Zechariah 14:3, 4)
Lift your heads, gates, and be raised up, doors of the world, so that the King of Glory may come in! Who is this King of Glory? Jehovah, strong and heroic, Jehovah, a hero in war. (Psalms 24:7–10)
On that day Jehovah Sabaoth will become an ornate crown and a beautiful diadem for the remnant of his people. (Isaiah 28:5)
I will send you Elijah the prophet before the great day of Jehovah comes. (Malachi 4:5)
There are other passages as well where it says that the day of Jehovah is great and near, like Ezekiel 30:3; Joel 2:11; Amos 5:18, 20; and Zephaniah 1:7, 14, 15, 18.
