2 Samuel Ch. 14
David was able to discern that the words spoken by the woman of Takoa were words given to her by Joab.
2 Samuel Ch. 13
Even though David was a man of God, he did not see that Amnon, his oldest son, loved his half-sister Tamar.
Even though David was a man after God’s own heart, he did not see everything.
Any Christian that says that they see everything, does not see as they should.
