'Numbers' in the Bible

And these are the numbers of the bands that were ready armed to the war, and came to David to Hebron, to turn the kingdom of Saul to him, according to the word of the LORD.

And these are the numbers of them according to the house of their fathers: Of Judah, the captains of thousands; Adnah the chief, and with him mighty men of valour three hundred thousand.

My mouth shall shew forth thy righteousness and thy salvation all the day; for I know not the numbers thereof.
