Charles H. Spurgeon on Psalms 22:30

"A seed shall serve him." This figurative expression signifies Christ and his people, who yield true obedience to God —they are called by this name in a spiritual and figurative, but most appropriate sense. The idea is taken from the operations of the husbandman who carefully reserves every year a portion of his grain for seed. Though it be small, compared with all the produce of his harvest, yet he prizes it very highly and estimates it by the value of that crop which it may yield in the succeeding autumn. Nor does he look only to the quantity, he pays particular regard to the quality of the seed. He reserves only the best, nay, he will put away his own if spoiled, that he may procure better. The very smallest quantity of really good seed, is, to him, an object of great desire, and if by grievous failure of crops, he should not be able to procure more than a single grain, yet would he accept it thankfully, preserve it carefully, and plant it in the most favourable soil. Such is the source from which the metaphor is taken. John Stevenson.
