Genesis 38:1 It happened at that time that Judah went down from his brothers and turned aside to a certain Adullamite, whose name was Hirah. There Judah saw the daughter of a certain Canaanite whose name was Shua. He took her and went in to her, and she conceived and bore a son, and he called his name Er. She conceived again and bore a son, and she called his name Onan. Yet again she bore a son, and she called his name Shelah. Judah was in Chezib when she bore him. And Judah took a wife for Er his firstborn, and her name was Tamar. But Er, Judah’s firstborn, was wicked in the sight of the LORD, and the LORD put him to death. Then Judah said to Onan, “Go in to your brother’s wife and perform the duty of a brother-in-law to her, and raise up offspring for your brother.” But Onan knew that the offspring would not be his. So whenever he went in to his brother’s wife he would waste the semen on the ground, so as not to give offspring to his brother. And what he did was wicked in the sight of the LORD, and he put him to death also. Then Judah said to Tamar his daughter-in-law, “Remain a widow in your father’s house, till Shelah my son grows up”—for he feared that he would die, like his brothers. So Tamar went and remained in her father’s house.
Judah marries a Canaanitish woman, who bears him three sons. He marries his eldest son to Tamar. He being wicked is slain by God. The second son is commanded to marry her. His wickedness, and death. He promises her his third son, but performs not. She by a subtle practice commits incest with him. He gives her a pledge. She is found with child; Judah commands her to be burnt. She brings to her father the pledge. He acknowledges it; acquits her, and condemns himself. She brings forth two sons. (Jamieson-Fausset-Brown)
Judah, the fourth-born son of Jacob through Leah (Reuben, Simeon, and Levi were before him), had not yet distinguished himself as someone great among his brothers. He was the one who suggested they sell Joseph into slavery. Through an ungodly and unwise marriage to a Canaanite woman, Judah fathered three sons: Er, Onan, and Shelah. It is not surprising that Judah chose a Canaanite wife for his son Er, since he himself was married to a Canaanite. We are never told what Er’s wickedness was, but obviously it was evil enough that God brought immediate judgment upon him. Growing up with a father from such a troubled family and with a mother who was a Canaanite did not help Er to live a godly life. (Guzik)
It is hard to imagine that the ancestral line of Jesus came through Judah. God’s plans and purposes are mysterious at best when we try to account for the reasons why. It is good for us to know He is God, He is Holy, and what He does is Holy and Just. This chapter reveals to us that a life lived apart from honor and glory to God, and trust and reliance on God will not have blessings, but rather have heartache, trials, and troubles without hope, peace, or joy for the soul. Judah chose to live his life apart from God and how it turns out for him and his children is recorded. We are given examples like this in scripture to warn us of worldly attachments and want of what it has to offer more than our want to honor and glorify God. It is not hard to discern or recognize lives that are apart from the want to honor and glorify God for the things people do and the things they say are contrary to God’s Word. This world will offer what it can not give – hope, peace, joy, love, kindness, gentleness, purpose, and soul-deep satisfaction. These will never be found apart from Jesus Christ. We may think we have found a lasting peace in what this world has to offer – money, prosperity, recognition, power, position…. but our souls will never find that lasting hope and peace in these temporal worldly offers.
Scripture is clear repent (turn away) from this life of worldliness and humble yourself before the throne of grace and mercy seeking forgiveness, believing in and trusting in, and relying on Jesus Christ alone. True peace comes to the soul that has purposed to honor and glorify Jesus Christ in all they think, say, and do.
