'Knoweth' here means more than knowing about — it means God is intimately acquainted with, watching over, caring for. The righteous path is personally shepherded by God. The other path is abandoned.
Memory phrase: God knows my path and walks with me.
Talk about it: What is the difference between someone knowing your name and someone truly knowing you?
Prayer: Thank You, God, that You know my path and walk with me. I choose Your way.
