Matthew 5:46-48 Young's Literal Translation (YLT)
46 `For, if ye may love those loving you, what reward have ye? do not also the tax-gatherers the same?
47 and if ye may salute your brethren only, what do ye abundant? do not also the tax-gatherers so?
48 ye shall therefore be perfect, as your Father who [is] in the heavens is perfect.
