'Practice' in the Bible

“Be careful not to practice your righteousness in front of people, to be seen by them. Otherwise, you will have no reward from your Father in heaven.

Therefore whenever you practice charitable giving, do not sound a trumpet in front of you, as the hypocrites do in the synagogues and in the streets, in order that they may be praised by people. Truly I say to you, they have received their reward in full!

But you, [when you] practice charitable giving, do not let your left hand know what your right hand is doing,

Then I will tell them plainly, "I never knew you. Get away from me, you who practice evil!'"

"Therefore, everyone who listens to these messages of mine and puts them into practice is like a wise man who built his house on a rock.

"Everyone who keeps on hearing these messages of mine and never puts them into practice is like a foolish man who built his house on sand.

The Son of Man will send his angels, and they will gather from his kingdom everything that causes others to sin and those who practice lawlessness

“Why do Your disciples violate the tradition (religious laws) handed down by the [Jewish] elders? For Your disciples do not [ceremonially] wash their hands before they eat.”

Therefore do whatever they tell you, and observe it. But don’t do what they do, because they don’t practice what they teach.
