'Tens' in the Bible

And the women, answering one another in their song, said, Saul has put to death his thousands and David his tens of thousands.

And Saul was very angry and this saying was unpleasing to him; and he said, They have given David credit for tens of thousands, and to me for only thousands: what more is there for him but the kingdom?

And the servants of Achish said to him, Is not this David, the king of the land? did they not make songs about him in their dances, saying, Saul has put to death thousands, and David tens of thousands?

Is this not David, who was named in their songs, when in the dance they said to one another, Saul has put to death thousands, and David tens of thousands?
