'Practice' in the Bible

"And take care not to practice your righteousness before people to be seen by them; {otherwise} you have no reward from your Father who is 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,

And then {I will say to them plainly}, 'I never knew you. Depart from me, you who practice lawlessness!'
