Context of Psalm 23:4 -

 Psalm 23 was written by David, who was a shepherd in his youth and eventually became of the ancient nation of Israel. (1 Samuel  17:34, 35; 2 Samuel 7:8) The psalm begins by describing Jehovah as Shepherd who leads, feeds, and refreshed his worshippers, just as a literal shepherd does his sheep. -PSALM 23:1-3. 

In Psalm 23:4, when highlighting God's protection, David switched from referring to God in the third person (he) to the second person (you). That subtle change emphasizes the intimate relationship David had with Jehovah. David knew that God cared for hi and that He was aware of his personal trials. As a result, David feared no harm.
