'Ten' in the Bible

So Elkanah her husband would say to her: "Hannah, why do you weep and why do you not eat? And {why are you heartsick}? Am I not better to you than ten sons?"

Saul summoned the army and mustered them at Telaim; two hundred thousand foot soldiers and ten thousand men of Judah.

Then Jesse said to his son David, "Please take for your brothers an ephah of this roasted grain and these ten loaves of bread, and bring [them] quickly to the camp for your brothers.

And these ten portions of cheese you will bring to the commander of the thousand; {find out how your brothers are doing}, and take their pledge."

And the women sang as they danced, and they said, "Saul has struck down his thousands, but David his ten thousands!"

{Saul became very angry}, and {this saying displeased him}, and he thought, "They have attributed to David ten thousands, but to me they have attributed thousands! {What more can he have but the kingdom}?"

The servants of Achish said to him, "[Is] not this David the king of the land? [Is] it not for this [one] that they sang in the dances, saying, 'Saul killed his thousands, but David his ten thousands?'"

So David sent ten young men, and David said to the young men, "Go up to Carmel and go to Nabal; {you will greet him in my name}.

{And then}, about ten days later, Yahweh struck Nabal and he died.

[Is] this not David about whom they sing in the dances, saying, 'Saul has killed his thousands, but David his ten thousands'?"
