2:9a path: The word is difficult to render. It is properly 'a path going round,' and hence used for the 'entrenchment' of a war camp, as 'wagon-defence' in 1Sam. 17:20. It is applied, as in Ps. 17:5; 23:3, to God's path for the saint, which does not always lead where we expect, or so that we can see straight on in it; and also to the shifting ways of the wicked, as ver. 18; and so in ver. 15, where the plural is rendered collectively 'course.'
