What Holy Bible tells about Polygny and Polyandry?

Answer 1

Basically, God wants a monagamous marriage (ie 1 man & 1 woman, for life) not multiple partners. Whenever there was a polygamous marriage there was trouble [eg Jacob with Leah and Rebekah]

Gen 2:21 [KJV] So the LORD God caused the man to fall into a deep sleep, and while he was asleep, he took part of the man's side and closed up the place with flesh.

Gen 2:22 Then the LORD God made a woman from the part he had taken out of the man, and he brought her to the man.

Gen 2:23 Then the man said,

"This one at last is bone of my bones

and flesh of my flesh;

this one will be called 'woman,'

for she was taken out of man."

Gen 2:24 That is why a man leaves his father and mother and unites with his wife, and they become a new family.

Gen 2:25 The man and his wife were both naked, but they were not ashamed.

Jesus stressed Monagamy with no divorce by one sex against the other sex:-

Mat 19:1[NET] Questions About Divorce

Now when Jesus finished these sayings, he left Galilee and went to the region of Judea beyond the Jordan River.

Mat 19:2 Large crowds followed him, and he healed them there.

Mat 19:3 Then some Pharisees came to him in order to test him. They asked, "Is it lawful to divorce a wife for any cause?"

Mat 19:4 He answered, "Have you not read that from the beginning the Creator made them male and female,

Mat 19:5 and said, 'For this reason a man will leave his father and mother and will be united with his wife, andthe two will become one flesh'?

Mat 19:6 So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate."

Mat 19:7 They said to him, "Why then did Moses command us to give a certificate of dismissal and to divorce her?"

Mat 19:8 Jesus said to them, "Moses permitted you to divorce your wives because of your hard hearts, but from the beginning it was not this way.

Christ is the Creator, the God of the Old Testament: He was there, so He should know:-

Col 1:13 [NET]He [Christ] delivered us from the power of darkness and transferred us to the kingdom of the Son he loves,

Col 1:14 in whom we have redemption, the forgiveness of sins.

Col 1:15 The Supremacy of Christ

He is the image of the invisible God, the firstborn over all creation,

Col 1:16 for all things in heaven and on earth were created by him - all things, whether visible or invisible, whether thrones or dominions, whether principalities or powers - all things were created through him and for him.

Col 1:17 He himself is before all things and all things are held together in him.

Col 1:18 He is the head of the body, the church, as well as the beginning, the firstborn from among the dead, so that he himself may become first in all things.

Col 1:19 For God was pleased to have all his fullness dwell in the Son

Col 1:20 and through him to reconcile all things to himself by making peace through the blood of his cross - through him, whether things on earth or things in heaven.

Answer 2

The Bible contains examples of polygyny, where a man has multiple wives, such as King Solomon. However, polyandry, where a woman has multiple husbands, is not specifically mentioned in the Bible and is generally not condoned in the Judeo-Christian tradition. Marriage in the Bible is typically portrayed as between one man and one woman.
