John Trapp on Ezekiel 42:20

Ver. 20. He meaſured it by the four ſides] The Church is fair and firm, for it is quadrangular: ſo is every true member thereof homo quadratus, four-ſquare, ſtedfaſt and unmovable, [non-Latin text not transcribed], always abounding in the Work of the Lord, &c. 1 Cor. 15. ult. his heart is fixed truſting in the Lord, Pſal. 112. He quits himſelf well in all eſtates, and comes of a gainer. Gold is purged in the fire, ſhines in the water: as, on t'other ſide, clay is ſcorcht in the fire, diſſolved in the water. The new Jeruſalem is ſaid to lye four-ſquare, Rev. 21.16. See the Note there.
