Q: Why does 2Samuel 12:8 say that
God gave wives (plural) to David if it was intended for man
to have only one wife?
A: Let's look at this verse in a bit of context.
2Samuel 12:7-8 And Nathan said to David, Thou art the
man. Thus saith the LORD God of Israel, I anointed thee king
over Israel, and I delivered thee out of the hand of Saul;
And I gave thee thy master's house, and thy master's wives
into thy bosom, and gave thee the house of Israel and of
Judah; and if that had been too little, I would moreover
have given unto thee such and such things.
If you carefully read these verses, you will see that it
is the wives of David's master, meaning King Saul, that were
given unto David by the Lord. That is, when David took over
the rule of the kingdom of Israel after the death of Saul,
Saul's entire household was available to David. However,
there is no record or indication that David ever took any of
them to wife. The Lord also told David that He had given to
David the house of Israel and the house of Judah. The idea
is that he could have chosen wives out of all the land of
Judah and Israel.
However, although David has access to the former king's
harem and although he had access to any available woman in
the entire kingdom, yet he stooped to take another man's
wife for his own and then proceeded to murder that man. He
is as the rich man who took the poor man's lamb for his
dinner--according to the parable Nathan had just told David.
It is true that God allowed bigamy in the Old Testament.
In Deuteronomy 21:15, the law makes certain requirements of
a man who has "two wives." However, as you point out, it was
not His plan from the beginning.
In Matthew 19:4-6, Jesus taught, "Have ye not read, that
he which made them at the beginning made them male and
female, And said, For this cause shall a man leave father
and mother, and shall cleave to his wife: and they twain
shall be one flesh? Wherefore they are no more twain, but
one flesh. What therefore God hath joined together, let not
man put asunder."
There was no plan to make three one flesh. That was man's
idea. The first example of bigamy in the Bible is with
Lamech (Genesis 4:19) who was of the ungodly line of Cain.
From the beginning, this practice had bad connections.
Finally, you ask if God would give to man something that
was not His original intention for him. Certainly, He will.
The Lord wanted the Israelites to enjoy and appreciate the
manna that He sent especially for them. However, they
continually complained and demanded meat. Finally, God gave
them quail to eat--loads and loads of quail (Numbers
11:31-33). However, getting what they lusted for from the
Lord brought with it a great cost. A plague killed many
people. We should always be careful when we insist on
getting only what we want. The beautiful rose of our dreams
may have many painful thorns. Thank you for the question.
Till He comes,
