'Thousands' in the Bible

He will appoint his officers over thousands and officers over fifties some will plow his fields, reap his harvest, and craft his war implements and equipment for his chariots.

As the women sang and played, they said, "Saul has struck down his thousands but David his ten thousands."

Saul was very angry and he did not like what the women sang. He told himself, "They have attributed tens of thousands to David, but to me they have attributed thousands. What else can he have but the kingdom?"

The officials of Achish told him, "Isn't this David, king of the land? Isn't this the one about whom they sang as they danced, "Saul has struck down his thousands, but David his ten thousands'?"

Saul told his officials who were standing around him, "Listen, men of Benjamin! Will Jesse's son also give fields and vineyards to all of you? Will he make all of you officers over thousands and officers over hundreds?

Investigate and find out all the hiding places there where he hides, and return to me with reliable information. Then I'll go down with you, and if he's in the land, I'll search him out among all the thousands of Judah."

Isn't this the same David about whom the maidens sang when they were dancing, "Saul has struck down his thousands, but David his ten thousands'?"
