You probably never noticed the quotation marks in the psalms. But look at these, now.
The God of glory thunders.
In His temple they all cry: "Glory!"
Finally I said, "Holy One, have mercy on me.
Heal my soul, for I have sinned against you."
My enemies cruelly mutter against me,
"When will he die, and his name perish?"
I say to you, my rock,
"Why have you forgotten me?"
The use of quotation marks gives a sense of dialogue taking place. It seems to me that it is used to highlight expression. I don't know if I can convey the same feeling.
Gather my dear one to Your Heart,
"My Love, My Life, My Jesus."
Warm them with blessings of wisdom;
Let them hunger for more of You.
Speak to them, "Come my children.
Seek the warmth of my church.
Hear the hymns of praise call to Me.
I will listen and answer. Trust."
