Run the way. — Plainly the psalmist means that he will not only be able to walk in the Divine way, but even to run in it when certain restraints are removed which now confine and check him. Hence we may understand, by the enlargement of the heart, not so much the expansion of the faculties as deliverance from oppressing fears, &c, as Psalms 4:1; Psalms 18:36, and render “when thou hast set my heart at large.” So the Prayer Book Version, “set my heart at liberty.”
