This description of God is exactly the opposite of that of America's national character. Our God is a God of truth, meaning He is unswervingly faithful. He is the Rock, implying One who is impervious to change. He is our Foundation, indicating One who provides firm footing in a way of life. He is our Fountain, the Source of a refreshing, productive way of life that He intends His people to use.
John W. Ritenbaugh
The Ninth Commandment
Speech equates to "teaching," so it includes God's Word, His commandments, His truth, and ultimately all of His instruction. Distill means to "run down," "flow," or "stream." This is a picturesque way of saying God sends His truth to cover the earth like dew!
