'Plan' in the Bible

but in the days of the sound of the seventh angel, when he will blow his trumpet, then God’s hidden plan will be completed, as He announced to His servants the prophets.”

For God has put it into their hearts to carry out His plan by having one purpose and to give their kingdom to the beast until God’s words are accomplished.

The plan of the city is a square, the length being the same as the breadth; and he measured the city furlong by furlong, with his measuring rod--it is twelve hundred miles long, and the length and the breadth and the height of it are equal.
