'Know' in the Bible

Moreover, that entire generation was gathered to their ancestors, and another generation grew up after them who did not know Yahweh or the work he had done for Israel.

in order that the generations of Israel would know war, to teach those {who had not experienced it} before):

They were [left] for testing Israel, to know [whether] they would keep the commands of Yahweh that he commanded their ancestors through the hand of Moses.

I will place a fleece of wool on the threshing floor. If there is dew on the fleece only, and all of the ground [is] dry, I will know that you will deliver Israel by my hand, just as you have said."

The angel of Yahweh said to Manoah, "If you keep me, I will not eat your food, but if you prepare a burnt offering for Yahweh, you can offer it (for Manoah did not know that he [was] an angel of Yahweh)."

His father and mother did not know that this [was] from Yahweh; he was seeking for an occasion against [the] Philistines. Now at that time [the] Philistines [were] ruling in Israel.

Then three thousand men from Judah went down to the cleft of the rock of Etam, and they said to Samson, "Do you not know that the Philistines [are] ruling over us? What [is] this [that] you have done to us?" And he said to them, "Just as they did to me, so I have done to them."

And she said to him, "[The] Philistines [are] upon you, Samson!" And he woke up from his sleep and said, "I will go out just like every other time and shake myself free," but he did not know that Yahweh had left him.

And Micah said, "Now I know Yahweh will make me prosperous, because the Levite has become my priest."

And they said to him, "Please inquire of God that we may know whether our journey that we [are] going on will be successful."

And the five men that went out to spy out the land ([that is], Laish) responded and said to their relatives, "Do you know that there are in these houses an ephod, teraphim, and an idol of cast metal? So then, consider what you must do."

Then ten thousand well-trained men from all Israel came out against Gibeah, and the battle became fierce; they did not know that disaster [was about to] {close in} on them.
