Charles H. Spurgeon on Psalms 104:14

For the service of man. The common version of these words can only mean for his benefit or use, a sense not belonging to the Hebrew word, which, as well as its verbal root, is applied to man's servitude or bondage as a tiller of the ground (Ge 3:17-19), and has here the sense of husbandry or cultivation, as in Ex 1:14, Le 25:39, it has that of compulsory or servile labour, the infinitive in the last clause indicates the object for which labour is imposed on man. J.A. Alexander.
