Mark 7:2-8 AMP

2 For they had seen that some of His disciples ate with common hands, that is, unwashed [with hands defiled and unhallowed, because they had not given them a ceremonial washing]–

3 For the Pharisees and all of the Jews do not eat unless [merely for ceremonial reasons] they wash their hands [diligently up to the elbow] with clenched fist, adhering [carefully and faithfully] to the tradition of [practices and customs handed down to them by] their forefathers [to be observed].

4 And [when they come] from the marketplace, they do not eat unless they purify themselves; and there are many other traditions [oral, man-made laws handed down to them, which they observe faithfully and diligently, such as], the washing of cups and wooden pitchers and widemouthed jugs and utensils of copper and beds–

5 And the Pharisees and scribes kept asking [Jesus], Why do Your disciples not order their way of living according to the tradition handed down by the forefathers [to be observed], but eat with hands unwashed and ceremonially not purified?

6 But He said to them, Excellently and truly [so that there will be no room for blame] did Isaiah prophesy of you, the pretenders and hypocrites, as it stands written: These people [constantly] honor Me with their lips, but their hearts hold off and are far distant from Me.

7 In vain (fruitlessly and without profit) do they worship Me, ordering and teaching [to be obeyed] as doctrines the commandments and precepts of men. [Isa. 29:13.]

8 You disregard and give up and ask to depart from you the commandment of God and cling to the tradition of men [keeping it carefully and faithfully].
