Hebrews 9:19 - Matthew Poole's English Annotations on the Holy Bible

For when Moses had spoken every precept to all the people according to the law: that the Old Testament was ratified by blood the Spirit proveth by instance, Moses as mediator having spoken every command, promise, and article of the covenant to all Israel, who came out of Egypt, according to God's charge, reading all to them out of the book, wherein by God's order he had written it; and the people declaring their assent and consent unto this covenant, as Exodus 24:3,4,7, as God covenanted and bound himself to his part of it. He took the blood of calves, &c.: the Mediator then took, according to the common rite in such ratifying acts, a sprinkling bush made of scarlet wool, cedar wood, and hyssop, Leviticus 14:4,6 Num 19:6,18; to which David alludeth, Psalms 51:7; and with this bunch sprinkles the blood and water (which he had received into basons from the sacrifices, killed by the first-born, for burnt-offerings and peace-offerings, and there mixed, Exodus 24:5,6 Le 9:3,4 14:51) on the altar, book of the covenant, and all Israel, Exodus 24:6-8, confirming and ratifying the covenant on God's part and theirs, as the words annexed, Hebrews 9:20, and Exodus 24:8, affirm: Behold the blood by which this covenant is made firm and inviolable. All this is but a shadow and type of the ratification of the new covenant with sinners by the death of Christ; he is the Mediator that brings God's testamental covenant to them; he dieth and puts it in force; by his blood ratifieth it on God's part and theirs, by his Spirit applying it to them, and sprinkling it on them; he brings home the testamental blessings to them, Hebrews 10:22, Hebrews 11:28 12:24 Isaiah 52:15 Ezekiel 36:25 1 Peter 1:2.
