Charles Spurgeon Commentary Galatians 3:15-16

"Brethren, I speak after the manner of men: Though it be but a man`s covenant, yet when it hath been confirmed, no one maketh it void, or addeth thereto. Now to Abraham were the promises spoken, and to his seed. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ." — Galatians 3:15-16 (ASV)

Brethren, I speak after the manner of men; Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto. Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.

Notice how important a single letter of the Scriptures may be. If vital doctrine may depend upon the use of a singular or plural noun, therefore let us jealously guard the smallest jot or tittle of the inspired Word of God.
