You people desire something and yet do not have it, [so] you murder [to get it]. You are envious [of what someone has] and [yet] are not able to obtain it, [so] you fight and quarrel [over it]. You do not have [what you want] because you do not ask [God for it].

But above everything else, my brothers, do not take oaths, not "by the heaven," nor "by the earth," nor by any other oath. But your "yes" should be [simply] "yes," and your "no," [simply] "no," so you do not fall under condemnation.
