2 Samuel 3:25
Thou knowest Abner the son of Ner, that he came to deceive thee, and to know thy going out and thy coming in, and to know all that thou doest.
2 Samuel 3:25 (KJV)
Context
The book of 2 Samuel records King David’s reign after Saul’s death, a time of political struggle and the uniting of the kingdom. Abner, the son of Ner, had commanded Saul’s army and long opposed David. Now he had come to David, claiming to want peace. Joab, David’s military leader, warns David that Abner’s visit was not honest. Joab says Abner came to deceive David and to learn his habits and plans.
Meaning
The phrase “thy going out and thy coming in” means knowing a person’s daily routines and activities. Joab charges that Abner wanted to spy on David, to discover his movements and everything he did. The warning is that Abner’s loyalty could be false, and his knowledge could be used to harm David. This shows the danger of trusting someone whose past actions prove him cunning and changeable.
Biblical connections
This verse does not name God, but the wider story shows David depending on divine wisdom in difficult situations. Throughout 2 Samuel, David seeks God’s guidance when facing enemies and uncertain allies. The warning against deception also appears in other places, such as Proverbs, where believers are told to guard their hearts and be wise about whom they trust.
Application
Discernment is essential. Like Joab urged David to examine Abner’s motives, believers must ask God for wisdom when forming relationships or making decisions. Trust in God should be deep, but that does not mean being naive about human sin. The Bible calls God’s people to be wise and alert, not suspicious of everyone, but careful and prayerful.
Seek God’s wisdom before trusting someone with important information.
Watch for patterns of dishonesty or shifting loyalty.
Rely on God’s protection rather than on human cleverness alone.
Reflection
God protects His anointed. David was not fooled by Abner’s scheme, and the Lord kept him safe. Believers can rest in the same faithfulness, knowing that God sees hidden motives and guards those who walk with Him. This verse encourages prudence without fear, and trust in God without blindness to evil.
