It is impossible to say what particular yoke the writer is thinking about. The persecutions inflicted on Jeremiah have been cited in illustration of this passage; and although we may not be able to ascribe the poem to the great prophet, his toils and troubles will serve as instances of the truth of the words of the anonymous writer, for undoubtedly his sympathies were quickened while his strength was ripened by what he endured. If we will have a definite meaning the yoke may stand for one of three things--for instruction, for labour, or for trouble. The sentence is true of either of these forms of yoke. We are not likely to dispute the advantages of youthful education over that which is delayed till adult age; but even if the acquisition of knowledge is here suggested, we cannot suppose it to be book knowledge, it must be that got in the school of life. Thus we are brought to the other two meanings. Then the connection excludes the notion of pleasant, attractive work, so that the yoke of labour comes near to the burden of trouble. This seems to be the essential idea of the verse. Irksome work, painful toil, forced labour partaking of the nature of servitude--these ideas are most vividly suggested by the image of a yoke. And they are what we most shrink from in youth. Inactivity is then by no means sought or desired. The very exercise of one's energies is a delight at the time of their fresh vigour. But this exercise must be in congenial directions, in harmony with one's tastes and inclinations, or it will be regarded as an intolerable burden. Liberty is sweet in youth; it is not work that is dreaded, but compulsion. Youth emulates the bounding energies of the war horse, but it has a great aversion to the patient toil of the ox. Hence the yoke is resented as a grievous burden; for the yoke signifies compulsion and servitude. Now, as a matter of fact, this yoke generally has to be borne in youth. People might be more patient with the young if they would but consider how vexatious it must be to the shoulders that are not yet fitted to wear it, and in the most liberty-loving age. As time passes custom makes the yoke easier to be borne; and yet then it is usually lightened. In our earlier days we must submit and obey, must yield and serve. This is the rule in business, the drudgery and restraint of which naturally attach themselves to the first stages. If older persons reflected on what this must mean at the very time when the appetite for delight is most keen, and the love of freedom most intense, they would not press the yoke with needless harshness.
