And the door, six cubits.
A wide way to God
The porch, at which was an ascent to the temple, had a gate belonging to it. This gate was six cubits. Now, some may object, and say, Since the way to God by these doors was so wide, why doth Christ say the way and gate is narrow? Answer. The straitness, the narrowness, must not be understood of the gate simply, but because of that cumber that some men carry with them, that pretend to be going to heaven. Six cubits! What is sixteen cubits to him who would enter in here with all the world on his back? (John Bunyan.)
