Chapter and verse divisions were not part of the original books of the Bible. They’re generally helpful as locators (the poor Preacher of Hebrews even says “But someone somewhere…” in Hebrews 2:6), but we can miss connections if we follow them too closely.
Luke put the stories of blind Bartimaeus (not named in Luke but in the other Gospels) and Zacchaeus back-to-back because we’re supposed to see the connections between them.
These two men are both unable to see.
They’re both desperate to get to Jesus.
They both desperately need Jesus.
These two men are quite different: one is a blind beggar, and the other is a powerful, rich, and corrupt tax collector.
Both leave drastically changed after meeting Jesus.
