John Trapp on Ezra 6:19

Verſe 19. And the children of the captivity] So the returned captives are called, Firſt, to keep ſtill afoot the remembrance of their late miſery, leſt they ſhould deſpiſe the chaſtening of the Lord, Heb. 12.5. Secondly, to inmind them of that ſignal mercy of their returne to their owne Countrey. Hence doth the Evangeliſt Matthew ſo oft mention their tranſportation to Babylon, and rings it in the eares of his ungrateful Countrey-men, Mat. 1.11, 12, 17.

Kept the Paſſeover] In remembrance, that the puniſhing Angel paſſed over their Anceſtours in Egypt, Exod. 12. and for confirmation of their faith in Chriſt the true Paſchal Lamb. Haſt thou eſcaped a danger? offer a Paſſeover. Hath Chriſt delivered thee from the wrath to come? keep the Feaſt with the unleavened bread of ſincerity and truth, 1 Cor. 5.8.

Ʋpon the fourteenth day of the firſt moneth] See Exod. 12.2. with the Note.
