3 Heb “one who walks blamelessly.”
4 Heb “one who speaks truth in his heart”; or “one who speaks truth [that is] in his heart.” This apparently refers to formulating a truthful statement in one’s mind and then honestly revealing that statement in one’s speech.
5 Hebrew literature often assumes and reflects the male-oriented perspective of ancient Israelite society. The principle of the psalm is certainly applicable to all people, regardless of their gender or age.
6 Heb “he does not slander upon his tongue.” For another example of רָגַל (ragal, “slander”) see 2 Sam 19:28.
7 Or “his fellow.”
8 Heb “and he does not lift up an insult against one who is near to him.”
