In Genesis 21:14, this signifies the state of wandering in the beginning, of people who have been introduced into the doctrinals of faith. (Arcana Coelestia 2679)

'Knowledge of the Lord' concerns the universal nature of all things of doctrinal teachings and therefore of all things of the church. All worship derives its life and soul from this knowledge, for the Lord is in heaven, the church, and in all of worship.
