He will not allow your foot to be moved. He who keeps you will not slumber.
He will not suffer thy foot to be moved. Though the paths of life are dangerous and difficult, yet we shall stand fast, for Jehovah will not permit our feet to slide; and if he will not suffer it we shall not suffer it. If our foot will be thus kept we may be sure that our head and heart will be preserved also.
He will not suffer thy foot to be moved: he that keepeth thee will not slumber. (b) He shows that God's providence not only watches over his Church in general, but also over every member of it.
The psalmist lifts his eyes to the holy mountains of his native land and asks: whence will my help come? His own longing desire answers: from Jahve alone, Maker of heaven and earth, whose power reaches to the remotest corners of creation, in whom both willingness and power to help dwell.
