'Keep' in the Bible

But Peter said, "Ananias, why has Satan filled your heart to lie to the Holy Spirit, and to keep back part of the price of the land?

You received the law as it was ordained by angels, and didn't keep it!"

But some of the sect of the Pharisees who believed rose up, saying, "It is necessary to circumcise them, and to command them to keep the law of Moses."

Because we have heard that some who went out from us have troubled you with words, unsettling your souls, saying, 'You must be circumcised and keep the law,' to whom we gave no commandment;

that you abstain from things sacrificed to idols, from blood, from things strangled, and from sexual immorality, from which if you keep yourselves, it will be well with you. Farewell."

As they went on their way through the cities, they delivered the decrees to them to keep which had been ordained by the apostles and elders who were at Jerusalem.

When they had laid many stripes on them, they threw them into prison, charging the jailer to keep them safely,

but taking his leave of them, and saying, "I must by all means keep this coming feast in Jerusalem, but I will return again to you if God wills," he set sail from Ephesus.

But concerning the Gentiles who believe, we have written our decision that they should observe no such thing, except that they should keep themselves from food offered to idols, from blood, from strangled things, and from sexual immorality."
