Psalms 18:36

Thou hast enlarged my steps under me -The idea here is, “Thou hast made room for my feet, so that I have been enabled to walk without hindrance or obstruction. So inPsalms 31:8, “Thou hast set my feet in a large room.” The idea is, that he was before straitened, compressed, hindered in his goings, but that now all obstacles had been taken out of the way, and he could walk freely. That my feet did not slip -Margin, mine ancles. The Hebrew word here rendered in the text feet, and in the margin ancles, means properly a joint; small joint; especially the ancle. The reference here is to the ancle, the joint that is so useful in walking, and that is so liable to be sprained or dislocated.
