Albert Barnes Commentary Job 23:11

"My foot hath held fast to his steps; His way have I kept, and turned not aside." — Job 23:11 (ASV)

My foot has 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 that Orientals have in their feet and toes. By constant usage, they accustom themselves to use them for holding things in a way that seems almost incredible to us, and they make their toes perform almost the work of fingers. We bind our feet tightly from early childhood in tight shoes, and they become useless except for walking.

But Orientals use theirs differently. They seize an object with their toes and hold it fast. If, while walking, they see anything on the ground that they want 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 around for some object to seize, saw a small shrub, seized it with his toes, and held it fast to remain firm while the executioner performed his task. “Roberts.” So an Arab, when treading firmly or taking a determined stand, seems to take hold of or grasp the ground with his toes, giving a fixedness of position inconceivable to those whose feet are cramped by tight shoes. This may be the meaning here: that Job had fixed himself firmly in God’s footsteps and had adhered tenaciously to Him. Or, as Dr. Good renders it, In his steps will I rivet my feet.

And not declined - Turned aside.
