I was just thinking, is it not the book of Psalm is in the old testamate and is it that the old testamate was under the mosaic law, and we were lifted from the mosaic law or the mosaic law does not apply any more with the ransom sacrefice Jesus Christ.
This is what Jesus said according to their own translation of the holy scriptures...
Mathew 43 “Y OU heard that it was said, ‘You must love your neighbor and hate your enemy.’ 44 However, I say to YOU : Continue to love YOUR enemies and to pray for those persecuting YOU ; 45 that YOU may prove yourselves sons of YOUR Father who is in the heavens, since he makes his sun rise upon wicked people and good and makes it rain upon righteous people and unrighteous. 46 For if YOU love those loving YOU , what reward do YOU have? Are not also the tax collectors doing the same thing? 47 And if YOU greet YOUR brothers only, what extraordinary thing are YOU doing? Are not also the people of the nations doing the same thing? 48 Y OU must accordingly be perfect, as YOUR heavenly Father is perfect.
