Luke 2:16
And they came with haste, and found Mary, and Joseph, and the babe lying in a manger.
Cross-reference
Luke 2:7 describes the baby wrapped in cloths and lying in a manger — the shepherds find exactly this, confirming the angel's sign.
In Luke 2:12, the angel gave a sign — a baby in a manger. Here the shepherds find it exactly as promised, confirming the sign.
In Luke 19:32, the disciples find a colt as Jesus said — a similar pattern of obedient discovery and fulfillment of a specific instruction.
In Luke 22:13, the disciples find the room as Jesus told them — another instance of finding things exactly as predicted, echoing the shepherds' experience.
In Matthew 2:11, the Magi also find Jesus with Mary — both shepherds and wise men come to worship the newborn King, reinforcing the theme of humble adoration.
In Matthew 8:20, Jesus has no place to lay his head — the manger in Luke 2:16 already shows his humble start, and this later verse deepens that picture of homelessness.
