'Keep' in the Bible

because I know your readiness [to help], [concerning] which I keep on boasting to the Macedonians about you, that Achaia has been ready [to help] since last year, and your zeal has stirred up the majority [of them].

And [when I] was present with you and was in need, I did not burden anyone, for the brothers who came from Macedonia supplied my need, and in everything I kept myself from being a burden to you, and will keep [myself from being a burden].
