KJV: 13 “But woe unto you, scribes and Pharisees, hypocrites! for ye shut up the kingdom of heaven against men: for ye neither go in yourselves, neither suffer ye them that are entering to go in. 14 Woe unto you, scribes and Pharisees, hypocrites! for ye devour widows' houses, and for a pretence make long prayer: therefore ye shall receive the greater damnation. ”

NIV: 13 Woe to you, teachers of the law and Pharisees, you hypocrites! You shut the door of the kingdom of heaven in people’s faces. You yourselves do not enter, nor will you let those enter who are trying to.

ESV: 13 But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people's faces. For you neither enter yourselves nor allow those who would enter to go in.

CSB: 13 Woe to you, scribes and Pharisees, hypocrites! You shut the door of the kingdom of heaven in people’s faces. For you don’t go in, and you don’t allow those entering to go in.

Explanation

Matthew 23:14 conflates v 13 with Mark 12:40 (parallel Luke 20:47).

Mark 12:40 They devour widows’ houses and for a show make lengthy prayers.

Luke 20:47 They devour widows’ houses and for a show make lengthy prayers.

Result

Nothin is lost with the omission of Matthew 23:14 because it occurs in two other passages.
