Douay-Rheims Bible: Exodus — Introduction, Chapter Summaries and Notes by Richard Challoner
Chapter 28
SummaryThe holy vestments for Aaron and his sons.
[28:15] The rational of judgment. . . This part of the priest's attire, which he wore at his breast, was called the rational of judgment; partly because it admonished both priest and people of their duty to God, by carrying the names of all their tribes in his presence; and by the Urim and the Thummim, that is, doctrine and truth, which were written upon it; and partly because it gave divine answers and oracles, as if it were rational and endowed with judgment.
[28:30] Doctrine and Truth. . .Hebrew, Urim and Thummim: illuminations and perfections. These words, written on the rational, seem to signify the light of doctrine and the integrity of life, with which the priests of God ought to approach him.
