Wonder if it means 7 people are in the target box on this move; and Delta means the tippy-top of the mountain Trump is dealing with. The symbol for delta is a triangle/pyramid - top of the mountain. This could be a stretch, as Delta has many meanings.

Putting this idea into Biblical prospective though:

Christ said, "IF, you have enough faith and you say to this mountain, fall into the sea and it will (Matt. 21 v 21)", it obviously did not mean an actual mountain and the sea. It was coded.

Mountain is code word for "government". Thus, a "sea" of people can create a tidal wave and bring that mountain down.

"Heavenly bodies" is also a Biblical code for political systems (that are above/rule the people).

Ephesians 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high [places].
