Good post: What was the law of the land when our Father Jacob was deceived into taking two wives?
Gen 29:18-21
(18) And Jacob loved Rachel; and said, I will serve thee seven years for Rachel thy younger daughter.
(19) And Laban said, It is better that I give her to thee, than that I should give her to another man: abide with me.
(20) And Jacob served seven years for Rachel; and they seemed unto him but a few days, for the love he had to her.
(21) And Jacob said unto Laban, Give me my wife, for my days are fulfilled, that I may go in unto her.
Gen 29:25-27
(25) And it came to pass, that in the morning, behold, it was Leah: and he said to Laban, What is this thou hast done unto me? did not I serve with thee for Rachel? wherefore then have you beguiled me?
(26) And Laban said, It must not be so done in our country, to give the younger before the firstborn.
Do you believe Jacob sinned before God in taking more than one wife?
My concern is that hearing how some in this thread have regarded King David, they might likewise regard Jacob a sinner before God concerning the wife of his youth and half of the sons of Jacob/Israel illegitimate. But when God shows us in Revelations at the very end of the book, "The Bride," "The Lamb's Wife" he shows us those sons' names on the Gates of the city in the Kingdom of God. This would be an unfortunate thing for someone to hold on to, if their hope is in The Kingdom of God (Matt 6:33).
I contend that, Jacob by the power of the Holy Spirit walked in God's law to the best of his ability and even was careful to keep Due 21:15-17 which hadn't actually been penned by Moses yet. But Ruben's lust-driven idolatry even drove him to covet and commit adultery in defiling his father Jacob's bed (Gen 49:3-4). So God saw fit to take away his double portion for that reason and gave it to Rachel's (Jacob's beloved wife of his youth) first-born's sons of the Egyptian, Ephraim and Manasseh.
I only pen this to show that Jacob only ever intended to take one wife (even as Abraham) and circumstances outside of his immediate control caused him to have two wives in a situation a man of God never hopes for.
Lev 18:18
Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
And yet he covered his wives and maintained the integrity of his house within the order of God to the best of his ability. This is a man demonstrating the love of God in a very difficult situation. This is why I said in an earlier post that in certain situations where a man having more than one wife who becomes a Christian should not be admonished to divorce his wives and neither should he multiply any more wives after the fact.
Pro 4:7
Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding.
