Let's look closer at this name "Abishag":
Strong's Exhaustive Concordance writes:
From 'ab and shagah; father of error (i.e. Blundering); Abishag, a concubine of David -- Abishag.
see HEBREW 'ab
see HEBREW shagah
"Ab" means Father, as in "Abba", which means "Daddy":
"And he said, Abba, Father, all things are possible unto thee; take away this cup from me: nevertheless not what I will, but what thou wilt." (Mark 14: 26)
Because Jesus became sin for us (2 Corinthians 5: 21), He was orphaned from God the Father at the Cross:
"And at the ninth hour Jesus cried with a loud voice, saying, Eloi, Eloi, lama sabachthani? which is, being interpreted, My God, my God, why hast thou forsaken me?" (Mark 15: 34)
We can now receive His Spirit of adoption:
"For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father." (Romans 8: 15)
"And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father." (Galatians 4: 6)

This Word "Shagah" takes the following three letters:
Shin speaks of The Divine Trinity -- Father, Son, and Holy Spirit
Gimel speaks of transportation, being carried, as on a camel
Heh speaks of God's grace.
In the midst of your error, God brings us His grace!
More specifically, this verb "shagah" is also translated "sin out of ignorance".
Leviticus 4 treats this issue of sinning out of ignorance, or unwittingly, in the following passage:
"1And the LORD spake unto Moses, saying, 2Speak unto the children of Israel, saying, If a soul shall sin through ignorance against any of the commandments of the LORD concerning things which ought not to be done, and shall do against any of them:" (Leviticus 4: 1-2)
To sin inadvertentlyu or "through ignorance" speaks to sinning that is not wilful or purposeful, that you did not know.
In effect, we are all sinners because of what Adam did, eating from the Forbidden Fruit (Genesis 3: 1-6)
Yet even though Adam sinned wilfully, we can all receive grace through Christ:
"But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. 16And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification. 17For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ." (Romans 5: 15-17)
Sin cannot stop God's grace from flowing into our lives; otherwise, no one would get saved! What stops God's grace is the notion that we can earn it, or that we have to earn it:
"Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace." (Galatians 5: 4)
Our efforts to be justified by the law, not our sin, cause us to fall from grace.
