1 Corinthians 7:18 - Coke's Commentary on the Holy Bible

Is any man called being circumcised?— This is a very pertinent digression, as it so directly contradicts the notion which prevailed among the Jews, that embracing the true religion dissolved all the relations which had before been contracted; whereas the Apostle here declares, that the Gospel left them in this respect just as it found them; increasing, instead of lessening, the obligations they were under to a faithful and affectionate discharge of their correspondent duties. The word επισπασθω has an evident relation to attempts like those referred to 1 Maccab. 1 Corinthians 1:15 which it is not necessary more particularly to illustrate. See Doddridge, Hammond, and Wall.
