One of the arguments people use to minimize the sinfulness of modern-day polygamy—especially in Africa—is the apparent blind eye God has towards it in the Old Testament. John Reisinger writes:

“There is no instance in the Old Testament Scripture that suggests, in any way, that polygamy was a sin. This does not prove that polygamy was not a sin, but it does prove that God never treated it as a sin.”

John Mbiti is even more direct:

"Christians who uphold monogamy as the only acceptable form of marriage before God, tell us that this is what the Bible teaches. They go on to tell us that polygamy is a sin. I have searched the Bible carefully and one of the staggering things concerning marriage is that the Bible does not treat marriage in terms of either monogamy or polygamy."
