ESV: And Jesus, looking at him, loved him, and said to him, “You lack one thing: go, sell all that you have and give to the poor, and you will have treasure in heaven; and come, follow me.”

CSB: Looking at him, Jesus loved him and said to him, “You lack one thing: Go, sell all you have and give to the poor, and you will have treasure in heaven. Then come, follow me.”

Internal evidence

The phrase was probably added from Mark 8:34,. “Then he called the crowd to him along with his disciples and said: ‘Whoever wants to be my disciple must deny themselves and take up their cross and follow me.’”

UBS gives the omission of the words an A rating.
