Matthew Poole and continuators on Deuteronomy 6:18

18 And thou shalt do that which is right and good in the sight of the LORD that it may be well with thee, and that thou mayest go in, and possess the good land which the LORD sware unto thy fathers:

Not that which is right in thine own eyes, as many superstitious and sinful practises seem right and good to evil minded men. Let Gods will and word, and not thine own fancy or invention, be thy rule in Gods service. Good actions are oft said to be right in Gods sight, as Ier. 34. 15. Act. 4. 19. and evil actions are oft said to be right in our own eyes, as Deut. 12. 8. Iudg. 17. 6.
