EXPOSITION
THE FIRST PASSOVER. Having received the Divine directions as to the new rite, if not with all the fulness ultimately given them, yet with sufficient fulness for the immediate purpose, Moses proceeded to communicate the Divine Will to the people under his protection. Having already aroused the jealousy and hatred of Pharaoh, he could not summon a general assembly of the people, but he ventured to call a meeting of the elders, or heads of principal families, and through them communicated the orders which he had received to the entire nation. We find, in the directions which he gave, two small points which are not comprised in the record of God's words to him.
1. The designation of the "hyssop," as the instrument, by which the blood was to be placed on the side-posts and lintel (Exodus 12:22); and,
2. The injunction not to quit the house "until the morning." These points may have been contained in the original directions, though omitted from the record for brevity; or they may have been added by Moses of his own authority. On the other hand, several very main points of the original directions are not repeated in the injunctions given to the elders, though there can be no doubt that they were communicated.
