hope: the good outcome someone waits for, and most often the one who is being waited on
This is a rare word for hope, used only five times, and it leans a particular way. The commoner Hebrew word for hope (תִּקְוָה) usually names the expectation a person holds. This one usually names the one the expectation rests on: three of its five uses address the LORD directly as "Hope of Israel," which is closer to "the one Israel is waiting on" than to any feeling.
The other two uses are the plainer kind. Ezra is told that "there is hope for Israel" even after a national failure, and a prayer of David says that human life passes like a shadow with nothing lasting to count on. In both, the word points ahead to an outcome that is still open.
What holds the two together is waiting. The verb behind it (קָוָה) means to wait for something, so hope here is not optimism about how things feel but a settled looking toward what is coming, or toward the one who is bringing it.
