Helem] It is likely that Helem and Hen were the same as were called Heldai and Josiah, vers. 10. a memoriall] For a publique monument and remembrance; either of their liberalitie and pietie in offering gold and silver unto Christ; or of their incredulitie and hardnesse of heart, who would not beleeve the promises without such a visible assurance; or of the typicall coronation of Joshua, that the crowns, as they were set upon his head for to signifie the Messiah, so should they be hung up in the Temple for a monument, to put all spectators in mind of what was promised, and to be expected shortly: Or, as Junius, to be a testimonie and confirmation of Gods favourable acceptance of all such as should come from a farre to worship in the Temple, and joyn themselves to the people of God; whether from Babylon, as these Jews here named, or elsewhere from among the Gentiles, as is inferred in the next verse.
