For his God doth instruct him to discretion, [and] doth teach him. God gives the husbandman instruction and discretion how to sow his seed, at what time, and in a proper place; for this refers to what goes before; though some think a new act is here intended, namely, threshing or beating out of corn, rendering the words, "and he" (the husbandman) "beateth it out, according to the discretion", or "judgment, his God teaches him" ; which is expressed in general terms here, and is next particularly insisted on in the following verses Isa 28:27.
"Excutit illud ad eam rationem, [quam] Deus, ipsius docet eum", Piscator, Gataker; "vel colligat", &c.
