My foot hath held his steps - Roberts, in his Oriental Illustrations, and the Editor of the Pictorial Bible, suppose that there is an allusion here to the active, grasping power which the Orientals have in their feet and toes. By constant usage they accustom themselves to make use of them in holding things in a manner which to us seems almost incredible, and they make the toes perform almost the work of fingers. We bind ours fast from early childhood in our close shoes, and they become useless except for the purpose of walking. But the Orientals use theirs differently. They seize upon an object with their toes, and hold it fast. If in walking along they see anything on the ground which they desire to pick up, instead of stooping as we would, they seize it with their toes, and lift it up. Alypulle, a Kandian chief, was about to be beheaded. When he arrived at the place of execution, he looked round for some object on which to seize, and saw a small shrub, and seized it with his toes, and held it fast in order to be firm while the executioner did his office. "Roberts." So an Arab in treading firmly, or in taking a determined stand, seems to lay hold of, to grasp the ground with his toes, giving a fixedness of position inconceivable to those whose feet are cramped by the use of tight shoes. This may be the meaning here, that Job had fixed himself firmly in the footsteps of God, and had adhered tenaciously to him; or, as it is rendered by Dr. Good," In his steps will I rivet my feet."
And not declined - Turned aside.

My foot hath held his steps, his way have I kept - I have carefully marked his providential dealings; and in his way - his pure and undefiled religion - have I walked. I have not only been generally but particularly religious: I have attended carefully to the weightier matters of the law, and have not forgotten its slightest injunctions.
Coverdale is curious: - Nevertheles my fete kepe his path, his hye strete have I holden, and not gone out of it. The hye strete is highway, the causeway, or raised road; formed, as they anciently were, by stones in the manner of pavement. It has its name from the Latin strata, paved, via being understood: via lapidibus strata, "a way paved with stones:" hence street, a raised road or pavement either in town or country. And hence the four grand Roman or British roads which intersected this kingdom: viz. Watling street, Icknild or Ricknild street, Ermin street, and Fosse street. Some say these streets or roads were made by Bellinus, a British king. Fosse street began in Cornwall, passed through Devonshire, Somersetshire, and along by Titbury upon Toteswould, beside Coventry, unto Leicester; and thence by the wide plains to Newark and to Lincoln, where it ends. Watling street begins at Dover, passes through the middle of Kent, over the Thames by London, running near Westminster, and thence to St. Alban's, Dunstable, Stratford, Towcester, Weden, Lilbourn, Atherston, Wreaken by Severn, Worcester, Stratton, through Wales unto Cardigan, and on to the Irish sea. Ermin, or Erminage street, running from St. David's in Wales, to Southampton. Ricknild, or Icknild street, running by Worcester, Wycomb, Birmingham, Lichfield, Derby, Chesterfield, and by York, into Tynemouth. See Camden, Holinshed, and Minshieu.

My foot hath held his steps,.... Trod in the steps he has walked in; he followed God closely, imitated him in acts of holiness and righteousness, of mercy, kindness, and beneficence; and he continued therein; as he set his foot in the steps of God, which were to him for an example, he persisted therein; as he followed on to know him, so to imitate him, and walk worthy of him:
his way have I kept; the way he prescribed him, and directed him to walk in, the way of his commandments, which he observed constantly, and kept; though not perfectly, yet with great delight and pleasure, and so as not to be chargeable with any gross neglect of them, but in some sense to walk in all of them blameless, as not to be culpable before men:
and not declined: from the way of God, did not turn aside from it to the right or left, or go into crooked paths with wicked men, or wickedly depart from his God, his ways and worship, as David says, Psalm 18:21.

held--fast by His steps. The law is in Old Testament poetry regarded as a way, God going before us as our guide, in whose footsteps we must tread (Psalm 17:5).
