'Kinsmen' in the Bible

and all the Levitical singers, Asaph, Heman, Jeduthun, and their sons and kinsmen, clothed in fine linen, with cymbals, harps and lyres, standing east of the altar, and with them one hundred and twenty priests blowing trumpets

And the sons of Israel led away captive 200,000 of their kinsmen [of Judah]—women, sons, and daughters—and they also took a great quantity of spoil from them and brought it to Samaria.

Now therefore, hear me and return the captives whom you have captured from your brothers (fellow descendants of Israel, i.e. Jacob), for the burning anger of the Lord is against you.”

But there were too few priests and they were unable to skin all the burnt offerings; so until the other priests had consecrated themselves, their brothers, the Levites, helped them until the work was done. For the Levites were more upright in heart and more conscientious than the priests in consecrating themselves.

And stand in the holy place [of the priests] according to the sections of the fathers’ households of your fellow kinsmen the lay people, and according to the Levites, by division of [the families of] a father’s household.
