'Kingdom of Heaven' in the Bible

Blessed are they who are persecuted upon the account of righteousness: for their's is the kingdom of heaven.

Not every one that says to me, Lord, Lord, shall enter into the kingdom of heaven: but only they who do the will of my Father who is in heaven.

and wherever ye go, make this proclamation: the kingdom of heaven is nigh.

Again, the kingdom of heaven is like a treasure hid in a field: a man finds this treasure and buries it again, then goes in great joy, sells all that he hath, and purchases that field.

wo unto you, Scribes and Pharisees, hypocrites, who shut up the kingdom of heaven against men: for ye not only refuse to go in your selves, but hinder those that would.
