Assalamu Allaicomu dear brother.
Brother I am not sure am I wrong,I think you have already asked this question and many of brothers and sisters replyed you.
First of all brother we are not folowers of Bible,we are folowers of Allah Holy Words(Holy Quran),and Sunnah of our holy Prophet Mohammed s.a.w.s. SubhanAllah.
In the Holy Quran Allah subhan we teala sais:You can get marryed with those womens that are alowed for you,with two,with three,and with four,and if you are afraid that you will not be justice towerds them than only with one"(Surah An Nissa).This ayah is clear Allhamdulilalh and Allahs limits noone can breake Inshallah.
If we look better and if we use are wisdom and if we are thinking about our Holy religion Isalm it sais that Muslims must be modest so it means that for thier modesty and only servinfg to Allah it is enough that they marry with only one women,becasue their only role in this life is serving to Allah Almighty and marrying with more womens it would not be modesty.
If Allah alowed to man to get marryed with more than one women,it means the most four,it is becasue of that Muslim man can help to some sister Muslim sister if he has good financial state and not becasue of his personal interests.
We should always reamin modesty as much as we can.
The best example is our beloved Prophet Mohammed s.a.w.s.(peace be upon him) and his holy,modest,and blessed life.
In his early ages,when he was only 25 years old he can marryed with Khadiya8peace be upon her) whcih was 40 years and she was not so much beatiful.But still our Prophet mOhammed s.a.w.s decided for her,of his all piety and modesty SubahnAllah.
With all other wives Prophet Mohammed s.a.w.s did not get marryed becasue of his personal wishes and interest (Neuzubillah),but becasue he get order from Allah to do that and on taht way to spread Islam.
Our Prophet Mohammed s.a.w.s was the most modest persone and the best of all mainkinds SubahnAllah and he should be example for all Muslims Inshallah.
Can you give us brother the links of web sites where it writes "a man can marry an infinite amount of women without any limits to how many he can marry".
These are not Islamic websites brother,and you should stay away from the Inshallah.
May Allah bless you.
Salam.
