Light and Truth
In Psalm 43:3, the psalmist calls upon God to send out His light and truth to lead him. This symbolizes divine guidance and revelation, which are necessary for the psalmist to find his way to God's holy hill and dwelling.
Light and truth are often associated with God's presence and His Word. They represent the clarity and direction that come from God, contrasting with the darkness of confusion and falsehood.
In biblical times, light was a common metaphor for understanding, purity, and divine presence, while truth was seen as the foundation of God's character and His covenant with His people.
