"time and for eternity; and I am accountable to God for the motives that prompt me to action.” Let this be his motto. Let the prayer of the psalmist be his prayer; “Set a watch, O Lord, before my mouth; keep the door of my lips. Incline not my heart to any evil thing.” [ Psalm 141:3, 4 .]— Testimonies for the Church 7:258, 259 . GW 448.2 Proper Remuneration for Ministers In this life those engaged in the ministry should receive fitting remuneration for their labor. They give their entire time, thought, and effort to the service of the Master; and it is not in the order of God that the wages paid them should be insufficient to supply the needs of their families. The minister who does his share according to his ability should receive his just due. GW 449"
"Upon every family, upon every individual Christian, is laid the duty of barring the way against corrupt speech. When in the company of those who indulge in foolish talk, it is our duty to change the subject of conversation if possible. By the help of the grace of God we should quietly drop words or introduce a subject that will turn the conversation into a profitable channel. COL 337.3"
Both passages deal with guarding one's speech. Psalms 141:3 speaks of controlling one's own mouth, while EGW speaks of influencing the conversation of others, but both relate to the broader theme of managing speech and its impact.
Psalms 141:5"Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil, which shall not break my head: for yet my prayer also shall be in their calamities."
"With a humble heart he received the rebuke, in harmony with his own words, “Let the righteous smite me; it shall be a kindness: and let him reprove me; it shall be an excellent oil.” Psalm 141:5 . He gave thanks and blessings because she advised him righteously. There are many who, when they are reproved, think it praiseworthy if they receive the rebuke without becoming impatient; but how few take reproof with gratitude of heart and bless those who seek to save them from pursuing an evil course. PP 667.3"
Ellen White directly references Psalms 141:5 in this passage.
