My God, my God, why have you forsaken me?

This week's ltg was receiving a bit of knowledge.

All these years that heard this famous cry, I always wondered why he says such a thing that seems like he is not with God anymore. Then, I see people's reactions "he's calling Elijah"

How did that reaction come out?

This time I decided to do some research and realized that it was part of psalms. And my Bible shows that as well.
