'Sober minded' in the Bible

but a lover of strangers, a lover of good men, sober-minded, righteous, kind, self-controlled,

that they may make the young women sober-minded, to be lovers of their husbands, lovers of their children,

The younger men, in like manner, be exhorting to be sober-minded;

And of all things the end hath come nigh; be sober-minded, then, and watch unto the prayers,
