what kind of 'waiting' was expected in ancient israelite culture and prayer practices?

The passage, plainly, with room to sit with it.

Psalm 27:14

“Wait for Yahweh. Be strong, and let your heart take courage. Yes, wait for Yahweh.”

This verse is the concluding encouragement of Psalm 27, a psalm traditionally attributed to King David. The psalm moves from a declaration of trust in God despite fear and enemies, to a plea for God's presence and help, ending with this call to patient waiting.
