To do thy will; to continue in faithful obedience to thee, notwithstanding all temptations to the contrary. Thy spirit is good, lead me; or rather, as it is exactly in the Hebrew, and as many both ancient and modern translators render it, let thy good Spirit lead me. Leave me not to my own blind and vain mind, or corrupt affections, neither give me up to the evil spirit, as thou didst Saul, but conduct me in all my ways by thy good, i.e. gracious and holy, Spirit. Into the land of uprightness; or, in plain or even land, or ground; in a straight and smooth path, that I may not stumble nor fall, either into sin or mischief. This is opposed to the crooked and rugged ways, in which sinners are said to walk. See Psalms 125:5 Proverbs 2:15 Isaiah 40:4.
