'Watch' in the Bible

Watch out, brothers, so that there won’t be in any of you an evil, unbelieving heart that departs from the living God.

See to it that no one falls short of God’s grace; that no root of resentment springs up and causes trouble, and by it many be defiled;

Watch out that you do not refuse the one who is speaking! For if those did not escape [when they] refused the one who warned [them] on earth, much less [will] we [escape], [if we] reject the [one who warns] from heaven,

Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you.
