Charles Ellicott Commentary Psalms 101:7

"He that worketh deceit shall not dwell within my house: He that speaketh falsehood shall not be established before mine eyes." — Psalms 101:7 (ASV)

Remain in my sight — i.e., stand as a courtier in the royal presence. Compare Homer:

“Hateful to me as gates of hell is he
Who hides one thing within his mind and speaks another.”
