What does Isaiah 9:1 mean?

But there won't always be darkness for those who are suffering. In the past, God humbled the lands of Zebulun and Naphtali, but in the future, he'll honor the region by the sea, across the Jordan, Galilee where outsiders live. Isaiah 9:1 - Modern Text Bible

(Isaiah promises that the time of hardship will end, especially for the northern regions that suffered first. Hope is coming to those who feel forgotten.)
