'Rank' in the Bible

Of Zebulun, such as went forth in the host, armed for war with all weapons of war, fifty thousand, keeping rank without double heart.

All of them men of war, keeping rank in battle array, came with a perfect heart to Hebron, to make David king over all Israel; and all the rest also of Israel were of one heart to make David king.

and with them their brethren of the second rank, Zechariah, Ben, and Jaaziel, and Shemiramoth, and Jehiel, and Unni, Eliab, and Benaiah, and Maaseiah, and Mattithiah, and Elipheleh, and Mikneiah, and Obed-Edom, and Jeiel, the doorkeepers;

And this hath been a small thing in thy sight, O God; and thou hast spoken of thy servant's house for a great while to come, and hast regarded me according to the rank of a man of high degree, Jehovah Elohim.
