Luke 11:34-36 contains the same teaching about the eye as the lamp — a parallel version of the same saying.

Psalm 86:11's request for an undivided heart parallels the healthy 'single' eye in Matthew 6:22 — both emphasize single-minded devotion to God.

Acts 26:18 describes opening eyes to turn from darkness to light — strong thematic match with the eye as the lamp bringing light to the body.

James 1:8 condemns the double-minded man — a direct contrast to the 'single' (haplous) eye in Matthew, which symbolizes wholehearted devotion.

Proverbs 4:25 exhorts looking straight ahead — the same focus metaphor as the 'single eye' in Matthew, linking physical sight to spiritual direction.

2 Corinthians 11:3 warns against being led astray from sincere devotion — similar to the healthy eye symbolizing single-minded focus in Matthew 6:22.
