'Maintaining' in the Bible

[So] know that Yahweh your God, he [is] God, the trustworthy God, maintaining his covenant and his loyal love with those who love him and with those who keep his commandments to a thousand generations,

maintaining a form of godliness, but denying its power. Avoid these [people].

maintaining your good conduct among the Gentiles, so that in [the things] in which they slander you as evildoers, by seeing your good deeds they may glorify God on the day of visitation.
