'Truly I Tell You' in the Bible

Any place that does not welcome you or listen to you, when you leave there, shake the dust off the soles of your feet as a testimony against them [breaking all ties with them because they rejected My message].”

I assure you and most solemnly say to you, whoever does not receive and welcome the kingdom of God like a child will not enter it at all.”

Jesus said, “I assure you and most solemnly say to you, there is no one who has given up a house or brothers or sisters or mother or father or children or farms, for My sake and for the gospel’s sake,

I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart [in God’s unlimited power], but believes that what he says is going to take place, it will be done for him [in accordance with God’s will].

Jesus said to him, “I assure you and most solemnly say to you, this very night, before a rooster crows twice, you will deny [that you even know] Me three times.”
