Clarke's Bible Commentary - Exodus 19:10 Verse 10. Sanctify them] See the meaning of this term, Exodus xiii. 2.
Let them wash their clothes] And consequently bathe their bodies; for, according to the testimony of the Jews, these always went together.
It was necessary that, as they were about to appear in the presence of God, every thing should be clean and pure about them; that they might be admonished by this of the necessity of inward purity, of which the outward washing was the emblem.
From these institutions the heathens appear to have borrowed their precepts relative to washings and purifications previously to their offering sacrifice to their gods, examples of which abound in the Greek and Latin writers. They washed their hands and clothes, and bathed their bodies in pure water, before they performed any act of religious worship; and in a variety of cases, abstinence from all matrimonial connections was positively required, before a person was permitted to perform any religious rite, or assist at the performance.
Matthew Henry Commentary Verses 9-15 - The solemn manner in which the law was delivered, was to impress the people with a right sense of the Divine majesty. Also to convince the of their own guilt, and to show that they could not stand in judgmen before God by their own obedience. In the law, the sinner discover what he ought to be, what he is, and what he wants. There he learns the nature, necessity, and glory of redemption, and of being made holy Having been taught to flee to Christ, and to love him, the law is the rule of his obedience and faith.
