'Assure' in the Bible

He also said, “I assure you: No prophet is accepted in his hometown.

Those slaves the master will find alert when he comes will be blessed. I assure you: He will get ready, have them recline at the table, then come and serve them.

I assure you: Whoever does not welcome the kingdom of God like a little child will never enter it.”

So He said to them, “I assure you: There is no one who has left a house, wife or brothers, parents or children because of the kingdom of God,

I assure you: This generation will certainly not pass away until all things take place.

And He said to him, “I assure you: Today you will be with Me in paradise.”
