My Purpose: WHY DID the Lineage NOT GO THROUGH Joseph instead of Judah??
Judah was the royal line. Are you asking why the messiah was to be born through the royal line or why Joseph didn't end up as the royal line?
Joseph wasn't the royal line because Jacob gave the blessing to Judah. (Genesis 49:8-12)
8 You, O Judah, your brothers shall praise; Your hand shall be on the nape of your foes; Your fathers sons shall bow low to you. 9 Judah is a lions whelp; On prey, my son, have you grown. He crouches, lies down like a lion, Like (Heb. labi, another word for lion.)the king of beasts (Heb. labi, another word for lion.) who dare rouse him? 10 The scepter shall not depart from Judah, Nor the rulers staff from between his feet; So that tribute shall come to him ( Shiloh, understood as shai loh tribute to him, following Midrash; cf. Isa. 18.7. Meaning of Heb. uncertain lit. Until he comes to Shiloh.) And the homage of peoples be his.
Why did Jacob give the blessing to Judah and not Joseph? I don't think the Bible really explains that.
In reality one big reason is that the author of Genesis 49 was from Judah.
