Bede : And when David had passed over to the other side, etc. When Jesus had passed over from this world to the Father, and remained untroubled in the height of the Father's kingdom, clearly separated far from the sight of mortals, and there was a great distance between Him, immortal victor over death, sitting at the right hand of the Father in the flesh as God, and those who, being mortal, miserable, and impious in this world, endeavored to fight against Him; He cried out through His apostles, preaching to the people of Israel, and to its scribes, urging them to rise from the slumber of their harmful lethargy and to respond to Him by believing. For Abner, who is interpreted as the lamp of the Father, shows those who should have ministered the light of truth to the people at that time. His father Ner, who is translated as a lamp, typifies their teachers who preceded in spiritually kindling and showing the light of legal knowledge to them and the people. — Commentary on Samuel
