Albert Barnes Commentary John 14:4

"And whither I go, ye know the way." — John 14:4 (ASV)

Where I go you know. He had so often told them that he was to die, and rise, and ascend to heaven, that they could not but understand it (Matthew 16:21; Luke 9:22; Luke 18:31–32).

The way you know. That is, the way that leads to the dwelling-place to which he was going. The way which they were to tread was to obey his precepts, imitate his example, and follow him (John 14:6).
