Jesus answered, “I assure you and most solemnly say to you, everyone who practices sin habitually is a slave of sin.

After Jesus had said these things, He was troubled in spirit, and testified and said, “I assure you and most solemnly say to you, one of you will betray Me and hand Me over.”

Jesus answered, “Will you [really] lay down your life for Me? I assure you and most solemnly say to you, before a rooster crows you will deny and completely disown Me three times.

I assure you and most solemnly say to you, that you will weep and grieve [in great mourning], but the world will rejoice. You will be sorrowful, but your sorrow will be turned into joy.
