There are three ways in which it is possible for one not to teach the truth. First, on the side of the teacher, who may either not know, or not love the truth; guarding against this, they say, “We know that Thou art true.”
Secondly, on the side of God, there are some who, putting aside all fear of Him, do not utter honestly the truth which they know respecting Him; to exclude this they say, “And teachest the way of God in truth.”
Thirdly, on the side of our neighbour, when through fear or affection any one withholds the truth; to exclude this they say, “And carest for no man,” for Thou regardest not the person of man.
