Adam Clarke Bible Commentary
Thou puttest my feet also in the stocks - בסד bassad, "in a clog," such as was tied to the feet of slaves, to prevent them from running away. This is still used in the West Indies, among slave-dealers; and is there called the pudding, being a large collar of iron, locked round the ankle of the unfortunate man. Some have had them twenty pounds' weight; and, having been condemned to carry them for several years, when released could not walk without them! A case of this kind I knew: The slave had learned to walk well with his pudding, but when taken off, if he attempted to walk, he fell down, and was obliged to resume it occasionally, till practice had taught him the proper center of gravity, which had been so materially altered by wearing so large a weight; the badge at once of his oppression, and of the cruelty of his task-masters!
And lookest narrowly - Thou hast seen all my goings out and comings in; and there is no step I have taken in life with which thou art unacquainted.
Thou settest a print upon the heels of my feet - Some understand this as the mark left on the foot by the clog; or the owner's mark indented on this clog; or, Thou hast pursued me as a hound does his game, by the scent.
Jamieson-Fausset-Brown Bible Commentary
stocks--in which the prisoner's feet were made fast until the time of execution (Jer 20:2).
lookest narrowly--as an overseer would watch a prisoner.
print--Either the stocks, or his disease, marked his soles (Hebrew, "roots") as the bastinado would. Better, thou drawest (or diggest) [GESENIUS] a line (or trench) [GESENIUS] round my soles, beyond which I must not move [UMBREIT].
John Gill Bible Commentary
Thou puttest my feet also in the stocks,.... Which is one kind of punishment of offenders, and a preservation of them from making their escape; and is a security and reservation of them for further punishment sometimes; and so Job looked upon his afflictions as a punishment for he knew not what, and with which he was so surrounded and enclosed, that there was no getting out of them any more than a man can whose feet are set fast in the stocks; and that he was here kept for greater afflictions still, which he dreaded. Aben Ezra interprets it, "thou puttest my feet in lime"; and this is followed by others (n), suggesting, as a man's steps in lime are marked and easily discerned, so were his by the Lord; but this seems to be foreign from the mind of Job, who would not make such a concession as this, as if his steps taken amiss were so visible:
and lookest narrowly into all my paths; so that there was no possibility of escaping out of his troubles and afflictions; so strict a watch was kept over him; see Job 7:19; according to Ben Gersom, this refers to the stocks, "it keeps all my ways", kept him within from going abroad about the business of life, and so may refer to the disease of his body, his boils and ulcers, which kept him at home, and suffered him not to stir out of doors; but the former sense is best:
thou settest a print upon the heels of my feet; either it, the stocks, made a mark upon his heels, with which they were pressed hard, as Gersom; or rather God set one upon them, afflicting him very sorely and putting him to an excruciating pain, such as is felt by criminals when heavy blows are laid upon the soles of their feet, to which the allusion may be; or else the sense is, that he followed him closely by the heels, that whenever he took a step, it was immediately marked, and observed by the Lord, as if he trod in his steps, and set his own foot in the mark that was left.
