Psalms 141:3

“Set a watch, O Lord, before my mouth, etc.] While praying, as Jarchi and Kimchi; that he might not utter any rash, unguarded, and unbecoming word; but take and use the words which God gives, even the taught words of the Holy Ghost; or lest, being under affliction and oppression, he should speak unadvisedly with his lips, and utter any impatient murmuring and repining word against God; or express any fretfulness at the prosperity of the wicked, or speak evil of them; especially of Saul, the Lord’s anointed, for the ill usage of him; keep the door of my lips; which are as a door that opens and shuts: this he desires might be kept as with a bridle, especially while the wicked were before him;…”

“Set a watch, O Lord, before my mouth - That I may not say anything rashly, unadvisedly, improperly. Compare Psalms 39:1. The prayer here is, that God would guard him from the temptation to say something wrong. To this he seems to have been prompted by the circumstances of the case, and by the advice of those who were with him. See introduction to the psalm. Compare the notes at Psalms 11:1. Keep the door of my lips - That my lips or mouth may not open except when it is proper and right; when something good and true is to be said. Nothing can be more proper than “this” prayer; nothing more desirable than that God should keep us from saying what we ought not to say. return to 'Top of Page'”

“141:3-5 Wisdom sometimes requires protection from oneself. One could say or think things that lead to the evil path (Prov 13:3; 21:23). • Wisdom opens itself to correction from godly people (see Prov 3:11; 9:8; 15:31; 19:25).”

“Set a watch: Psa 17:3-5, Psa 39:1, Psa 71:8; Mic 7:5; Jam 1:26, Jam 3:2 Psalms 141:4”

“The prayer now begins to be particularized, and that in the first instance as a petition fore the grace of silence, calling to mind old Davidic passages like Psa 39:2; Psa 34:14. The situation of David, the betrayed one, requires caution in speaking; and the consciousness of having sinned, not indeed against the rebels, but against God, who would not visit him thus without his deserving it, stood in the way of any outspoken self-vindication. In pone custodiam ori meo שׁמרה is ἅπ. λεγ., after the infinitive form דּבקה, עזבה, עצמה. In Psa 141:3 דּל is ἅπ. λεγ. for דּלת; cf. "doors of the mouth" in Mic 7:5, and πύλαι στόματος in Euripides. נצּרה might be imper. Kal: keep I pray, with Dag.…”
