Psalm 80: 3, 7, 19
(A thrice-repeated verse with a slight addition with each repeating of the verse.
They are addressing God; not merely God but the God of hosts; not merely the God of hosts but the Lord God of hosts; with each addition it becomes more specific and descriptive of the God they’re addressing. Seems like a very basic observation but each additional word(s) (of hosts; Lord) is a title of God that reveals something about Him and what it means in the context of the psalm, the relation and implications of the usage of that word/title of God. It could be easy to overlook, miss, skip but to pause for a moment and read with intent of understanding usage, context and implications, that shall benefit us much more than merely reading routinely or hurriedly.)
“3) Turn us again, O God, and cause Thy face to shine, and we shall be saved.
7) Turn us again, O God of hosts, and cause Thy face to shine, and we shall be saved.
19) Turn us again, O Lord God of hosts; cause Thy face to shine, and we shall be saved!“
