Younger
In general, birth order in the Bible reflects the progression of spiritual states, but the specifics of those states depends greatly on context: who the people in question are, and whether we’re talking about spiritual states as they flow to us from the Lord, or spiritual states as we advance through them to approach the Lord. For example, Esau was older than Jacob (by minutes, but it mattered), and as the elder represents a more internal spiritual state: the desire for good, and the ideas that flow from that desire. Jacob represents a more external state: the understanding of ideas that lead to good. The switched blessing, with Jacob getting the blessing Isaac meant for Esau, shows that to progress in life we need to put our understanding first for a while, though ultimately our loves will catch up and ultimately determine our true character. A similar thing happens when Jacob crosses his hands to give Ephraim, the younger of Joseph’s sons, the primary blessing over his older brother Manasseh. Both those cases describe blessings coming from the Lord, with the highest states coming from Him and extending down through lower states to get to us. There is a sort of opposite dynamic in the story of Leah and Rachel. There Jacob (representing the Lord himself, as a human, in His childhood) is advancing from more external states to more internal ones. In this case, then, the older daughter, Leah, represents a more external state which He had to work through to reach the more internal state represented by Rachael.
Micah 5
1
Now gather thyself in troops, O daughter of troops: he hath laid siege against us: they shall smite the judge of Israel with a rod upon the cheek.
2
But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.
3
Therefore will he give them up, until the time that she which travaileth hath brought forth: then the remnant of his brethren shall return unto the children of Israel.
4
And he shall stand and feed in the strength of the LORD, in the majesty of the name of the LORD his God; and they shall abide: for now shall he be great unto the ends of the earth.
5
And this man shall be the peace, when the Assyrian shall come into our land: and when he shall tread in our palaces, then shall we raise against him seven shepherds, and eight principal men.
6
And they shall waste the land of Assyria with the sword, and the land of Nimrod in the entrances thereof: thus shall he deliver us from the Assyrian, when he cometh into our land, and when he treadeth within our borders.
7
And the remnant of Jacob shall be in the midst of many people as a dew from the LORD, as the showers upon the grass, that tarrieth not for man, nor waiteth for the sons of men.
8
And the remnant of Jacob shall be among the Gentiles in the midst of many people as a lion among the beasts of the forest, as a young lion among the flocks of sheep: who, if he go through, both treadeth down, and teareth in pieces, and none can deliver.
9
Thine hand shall be lifted up upon thine adversaries, and all thine enemies shall be cut off.
10
And it shall come to pass in that day, saith the LORD, that I will cut off thy horses out of the midst of thee, and I will destroy thy chariots:
11
And I will cut off the cities of thy land, and throw down all thy strong holds:
12
And I will cut off witchcrafts out of thine hand; and thou shalt have no more soothsayers:
13
Thy graven images also will I cut off, and thy standing images out of the midst of thee; and thou shalt no more worship the work of thine hands.
14
And I will pluck up thy groves out of the midst of thee: so will I destroy thy cities.
15
And I will execute vengeance in anger and fury upon the heathen, such as they have not heard.
