Numbers 10:3

Observe GOD'S precept. Precepts and promises are sometimes joined together; not as if the LORD'S mercies were depending upon the desert of man, but to intimate that the LORD hath graciously appointed means to the end. The Psalmist hath drawn a nice, but proper distinction between the means, and the blessing on the means, when he pronounceth a blessing on those that know, not simply hear but know, the joyful sound. Psalms 89:15. Reader! pray be careful to mark the striking difference.
