Therefore Michal the daughter of Saul had no child unto the day of her death.
2 Samuel 6:23
But the king took the two sons of Rizpah the daughter of Aiah, whom she bare unto Saul, Armoni and Mephibosheth; and the five sons of Michal the daughter of Saul, whom she brought up for Adriel the son of Barzillai the Meholathite:
2 Samuel 21:8
Michal’s five sons were adopted; the reason she is raising Adriel’s sons is not given.
There are those that proclaim this as a contradiction in the KJV, but they always leave off the last part of the verse: “whom she brought up for Adriel”, they do so knowing that they are attempting to deceive.
Who can they deceive? Those who have not set their hearts to seek the Lord and diligently study his word.
