What does the Bible say about having a single eye?

In Luke 11:34, Jesus states, 'The light of the body is the eye; therefore, when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy body also is full of darkness.' This verse emphasizes the importance of having a focused and righteous perspective, where believers should look solely to God and His ways without distraction or divided attention. A single eye represents a commitment to seeking God's glory and truth, leading to spiritual illumination and understanding.
