Charles H. Spurgeon on Psalms 114:1

Israel went out of Egypt. This was an emblem of the Lord's people in effectual vocation, coming out of bondage into liberty, out of darkness into light, out of superstition, and idolatry, and profaneness, to the service of the true God in righteousness and true holiness; and from a people of strange language to those that speak the language of Canaan, a pure language, in which they can understand one another when they converse together, either about experience or doctrine; and the manner of their coming out is much the same, by strength of hand, by the power of divine grace, yet willingly and cheerfully, with great riches, the riches of grace, and a title to the riches of glory, and with much spiritual strength; for though weak in themselves, yet they are strong in Christ. —John Gill.
