Charles H. Spurgeon on Psalms 26:4

I have not sat with vain persons. There is a necessary commerce with men in buying and selling, or as the apostle says, "We must needs go out of the world, "but do not voluntarily choose the company of the wicked. 1Co 5:10. "I have written unto you not to keep company, "etc. 1Co 5:11. Do not be too familiar with them. What do Christ's doves among birds of prey? What do virgins among harlots? The company of the wicked is very defiling, it is like going among them that have the plague. "They were mingled among the heathen and learned their works." If you mingle bright armour with rusty, the bright armour will not brighten the rusty, but the rusty armour will spoil the bright. Pharaoh taught Joseph to swear, but Joseph did not teach Pharaoh to pray. Thomas Watson.
