The Lord said, "Because this people draws near with their mouth and with their lips to honor me, but they have removed their heart far from me, and their fear of me is a commandment of men which has been taught;
'These people draw near to me with their mouth, and honor me with their lips; but their heart is far from me.
He answered them, "Well did Isaiah prophesy of you hypocrites, as it is written, 'This people honors me with their lips, but their heart is far from me.
You have planted them, yes, they have taken root; they grow, yes, they bring forth fruit: you are near in their mouth, and far from their heart.
They come to you as the people come, and they sit before you as my people, and they hear your words, but don't do them; for with their mouth they show much love, but their heart goes after their gain.
Their tongue is a deadly arrow; it speaks deceit: one speaks peaceably to his neighbor with his mouth, but in his heart he lays wait for him.
In praying, don't use vain repetitions, as the Gentiles do; for they think that they will be heard for their much speaking.
They haven't cried to me with their heart, but they howl on their beds. They assemble themselves for grain and new wine. They turn away from me.
These words seemed to them to be nonsense, and they didn't believe them.
1 Timothy 6:20
Timothy, guard that which is committed to you, turning away from the empty chatter and oppositions of the knowledge which is falsely so called;
2 Timothy 2:16
But shun empty chatter, for they will proceed further in ungodliness,
for as he thinks about the cost, so he is. "Eat and drink!" he says to you, but his heart is not with you.
