I think you quoted that wrong, they actually dont do His Commandments...
Mat 15:7-9, "Hypocrites! Well did Isayah (29:13-14)* prophesy of you, saying: These people draw near to Me with their mouth and honor Me with their lips, but have removed their hearts far from Me. But in vain they do worship Me, teaching as doctrines the commandments of men."
*Isayah 29:13-14, "Therefore YHWH said: Because these people draw near to Me with their mouths and honor Me with their lips, but have removed their hearts far from Me, and their reverence to Me is taught by the precept of men; Therefore, behold, I will proceed to do a marvelous work among this people; a marvelous work and a wonder; for the wisdom of their wise men will perish, and the understanding of their prudent men, will be hid."
Mark 7:1-9, “And the Pharisees and some of the scribes assembled to Him, having come from Yerushalayim. And seeing some of His taught ones eat bread with defiled, that is, with unwashed hands, they found fault. For the Pharisees, and all the Yehuḏim, do not eat unless they wash their hands thoroughly, holding fast the tradition of the elders, and coming from the market-place, they do not eat unless they wash. And there are many other traditions which they have received and hold fast – the washing of cups and utensils and copper vessels and couches. Then the Pharisees and scribes asked Him, “Why do Your taught ones not walk according to the tradition of the elders, but eat bread with unwashed hands? And He answering, said to them, “Well did Yeshayahu prophesy concerning you hypocrites, as it has been written, ‘This people respect Me with their lips, but their heart is far from Me. And in vain do they worship Me, teaching as teachings the commands of men.’ Forsaking the command of YHWH, you hold fast the tradition of men. And He said to them, “Well do you set aside the command of YHWH, in order to guard your tradition."
You made it say the exact oppisite.
