Psalms 89:33-34

³³But I shall not scatter my mercy from him; and in my truth I shall not harm him. (But I shall not take away my love from him; and I shall be faithful to him.)

³⁴Neither I shall make unholy my testament; and I shall not make void those things that come forth of my lips. (Nor shall I break my covenant; and I shall not make void those things which come forth from my lips, that is, I shall not break my promises.)
