God gifts men wives and concubines. That in and of its self shows it isn't a sin. The fact that concubines were ok shows that if not just wives that men may have relations with multiple women. Women are to submit.
Concubine definition.
1. a woman who cohabits with a man to whom she is not legally married, especially one regarded as socially or sexually subservient; mistress.
2. (among polygamous peoples) a secondary wife, usually of inferior rank.
3. (especially formerly in Muslim societies) a woman residing in a harem and kept, as by a sultan, for sexual purposes.
Eddy, I prefer Scripture over modern dictionaries for Biblical definitions. Why? Because there is a tendency for people to commit the anachronistic fallacy by doing so.
Here is how one person put it (which basically expresses what I teach as well):
The Hebrew word for concubine is pilegesh, and it is used for an illicit sexual relationship, but only once.
For she lusted for her paramours, whose flesh is like the flesh of donkeys, and whose issue is like the issue of horses. (Ezekiel 23:20)
Here in Ezekiel 23:20, the Hebrew word for concubine is translated "paramours." A paramour is an illicit sexual lover indeed, and the context of this passage supports this translation. It is speaking of a woman with her male immoral partners (paramours). The "concubines," so to speak, are male here, not female, and this is the only time this word is used for males.
Every time pilegesh is used for a female, it is used for a woman who is married to a man. Keturah is called Abraham's concubine in 1 Chronicles 1:32 (piylegesh), but in Genesis 25:1 she is called Abraham's wife ('ishâh). David's ten concubines are indeed called concubines, but they are also called his wives by the Lord Himself (2 Samuel 12:11; 16:21-22). In Judges 19 & 20 the Levite's concubine "
played the harlot" (Judges 19:2) and left "
her husband" (Judges 19:3). She is called a concubine in Judges 19:1, 2, 9, 24, 25, 29; 20:4 and 5, yet at the same time, her male partner, the Levite, is called "
her husband" in Judges 19:3 and 20:4. Moreover, the concubine's father is called the "
father-in-law" (Judges 19:4, 7, 9), and the Levite is called the "
son-in-law" (Judges 19:5). Clearly, concubinage is displayed as a marital commitment.
So, what is the difference between a "wife" and a "concubine"? Wives are free, concubines are not. Scripture portrays concubinage as the marriage of a slave girl. Note Leviticus 19:20.
Whoever lies carnally with a woman who is betrothed to a man as a concubine, and who has not at all been redeemed nor given her freedom, for this there shall be scourging; but they shall not be put to death, because she was not free.
Betrothal depicts marriage (Deuteronomy 28:30), and here in Leviticus 19:20 we have the marriage (betrothal) of a slave girl to a man. Being a slave, she is called a concubine, and for this immoral act she is not killed as a free woman would be (Deuteronomy 22:23-24), "
because she was not free."
In Judges the concubine's husband is twice called "
her master" (Judges 19:26, 27). Other concubines are identified likewise. Bilhah, Jacob's concubine (Genesis 35:22), whom Rachel gave to him for a wife (Genesis 30:3-4), was a slave (Genesis 35:25 "
maidservant"). Likewise, Zilpah was a slave-wife (Genesis 35:26; 30:9). Marrying a slave girl was not only practiced; it was legislated in the law of God as well.
And if a man sells his daughter to be a female slave, she shall not go out as the male slaves do. If she does not please her master, who has betrothed her to himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, since he has dealt deceitfully with her. And if he has betrothed her to his son, he shall deal with her according to the custom of daughters. If he takes another wife, he shall not diminish her food, her clothing, and her marriage rights. And if he does not do these three for her, then she shall go out free, without paying money. (Exodus 21:7-11; see also Deuteronomy 21:10-14)
Notice it does not say, "He cannot take another wife." It says, "
If he takes another wife." Here we have another law concerning polygyny and it is not forbidden.
Although some today may view concubinage as an evil deed, Leah, in the Scriptures, viewed it as part of that which pleased the Lord.
And God listened to Leah, and she conceived and bore Jacob a fifth son. Leah said, "God has given me my wages, because I have given my maid to my husband." So she called his name Issachar. (Genesis 30:17-18)
Leah had given Zilpah, her maidservant, to Jacob as a wife because she perceived that she had stopped bearing children (Genesis 30:9). Yet, she continued to pray for more sons. God heard her plea ("God listened to Leah"), and Leah understood this to be a reward from the Lord for giving Jacob a concubine.

In essence, concubines are wives, but have a different status.
