2 Samuel 7:12-16 (NIV) says,
12 When your days are over and you rest with your ancestors, I will raise up your offspring to succeed you, your own flesh and blood, and I will establish his kingdom. 13 He is the one who will build a house for my Name, and I will establish the throne of his kingdom forever. 14 I will be his father, and he will be my son. When he does wrong, I will punish him with a rod wielded by men, with floggings inflicted by human hands. 15 But my love will never be taken away from him, as I took it away from Saul, whom I removed from before you. 16 Your house and your kingdom will endure forever before me; your throne will be established forever.’”
In this speech, God speaks to David using both second and third-person points of view. Beginning from verse 12, God uses the second-person point of view ('you' and 'your'), then transitions to third-person near the end of verse 12 to 15a ('he', 'him', and 'his'), and finally with second-person again in 15b and 16. Why?
