John Trapp on Nehemiah 10:28

Verſe 28. That had ſeparated themſelves] In Saint Pauls ſenſe, 2 Cor. 6.17. Come out from among them, and be ye ſeparate, &c. from ſuch ſtand off; Stand up from the dead, ſave your ſelves from this untoward generation, ſhun their ſinnes, leſt ye ſhare in their plagues. Theſe holy Separates (or Proſelytes) ſealed the Covenant, and became free deniſons of the Common-wealth of Iſrael; having right to all Gods Ordinances, Exod. 12.48. Such were Araunah the Jebuſite, 2 Sam. 24. Jether the Iſmaelite, 1 Chron. 7.17. with 2 Sam. 17.25. thoſe Acts 2.10. the Jewes called them Advenas Juſtitiae. Deodate interpreteth this text of ſuch Jewes as were come again out of Babylon, to ſerve the Lord, according to his Law. Others, of ſuch as had ſeparated themſelves from their Heathen-wives and children.

Their wives, their ſonnes, and their daughters] Theſe alſo were then, and ſtill may be Covenanters, as partakers of the benefit, 1 Tim. 6.2. and heirs together of the grace of life, 1 Pet. 3.7.

Every one having knowledge] Of their own miſery by ſinne, and of the great myſtery of godlineſſe.
