'Generations' in the Bible

These are their generations: the firstborn of Ishmael, Nebaioth; then Kedar, and Adbeel, and Mibsam,

His brothers by their families, when the genealogy of their generations was reckoned: the chief, Jeiel, and Zechariah,

The sons of Tola: Uzzi, and Rephaiah, and Jeriel, and Jahmai, and Ibsam, and Shemuel, heads of their fathers' houses, [to wit], of Tola; mighty men of valor in their generations: their number in the days of David was twenty-two thousand six hundred.

With them, by their generations, after their fathers' houses, were bands of the army for war, thirty-six thousand; for they had many wives and sons.

They were reckoned by genealogy, after their generations, heads of their fathers' houses, mighty men of valor, twenty thousand two hundred.

These were heads of fathers' [houses] throughout their generations, chief men: these lived in Jerusalem.

and their brothers, according to their generations, nine hundred fifty-six. All these men were heads of fathers' [houses] by their fathers' houses.

These were heads of fathers' [houses] of the Levites, throughout their generations, chief men: these lived at Jerusalem.

Remember his covenant forever, the word which he commanded to a thousand generations,

Of the Hebronites was Jerijah the chief, even of the Hebronites, according to their generations by fathers' [houses]. In the fortieth year of the reign of David they were sought for, and there were found among them mighty men of valor at Jazer of Gilead.
