Once again, Issachar is completely out of place considering where it was in Joshua, chapter 19, up north of Manasseh, between Zebulun and Naphtali. Nevertheless, this small tribe got one portion, next to the territory of Simeon, somewhere here in the south.
Baruch expounded the greatness of Israel with its vast territory as the house of God. This seems so out of place for the exiles in Babylon who had no land. However, it was both remembrance and aspirational. Baruch talked about the greatness of Israel with no bounds and immeasurable heights.
How then did they end up in the city of Jerusalem? Their explanation was simple. With the coming of King Nebuchadnezzar (605-562 BCE) of Babylon, they moved to safety in or around Jerusalem. They feared for their lives because of the Babylonian invasion with their Chaldean and Aramean troops. Thus they took refuge in Jerusalem. Obviously, they were a little out of place there with their strange life style ways.
This passage seems out of place here, since the healing of King Hezekiah is at the end of this chapter. This backwards moving of the sundial is the sign that Isaiah was to give to King Hezekiah. Instead of Isaiah crying out, this is an abbreviated version of what appeared to 2 Kings, chapter 20, with just the simple statement of Isaiah. This sundial had been installed by King Hezekiah’s father, King Ahaz (736-716 BCE). Since moving forward would not be difficult and was normal. However, if the shadow moved backward, that would be a strange. Thus the sundial moved back 10 intervals, indicating that the sun had moved backwards, which would have been miraculous. If they only knew that the earth was moving and not the sun, they would have been even more astonished.
