Isaiah 1:24 - “...saith the Lord, the Lord of hosts, the mighty One of Israel, Ah,” - Jer 1:6 , Jer 4:10 & Jeremiah 14:13 - “Then said I, Ah, Lord God!” - Jer 34:5 - “saying, Ah lord!” => “Ah-Men-N” is Egyptian for “Father-Son-Sprirt” - so “Amen” is literally saying ...“In the name of the Father, the Son and the Holy Ghost”

Isaiah 1:24

Therefore saith the Lord, the Lord of hosts, the mighty One of Israel, Ah, I will ease me of mine adversaries, and avenge me of mine enemies:

Jeremiah 1:6

Then said I, Ah, Lord God! behold, I cannot speak: for I am a child.
