1 Corinthians 7:37
Nevertheless he that standeth vstedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.
Nevertheless he that standeth stedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.
NKJV: Nevertheless he who stands steadfast in his heart, having no necessity, but has power over his own will, and has so determined in his heart that he will keep his virgin, does well.
ESV: But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed, he will do well.
ὃς δὲ ἕστηκεν ἑδραῖος ἐν τῇ καρδίᾳ, μὴ ἔχων ἀνάγκην, ἐξουσίαν δὲ ἔχει περὶ τοῦ ἰδίου θελήματος, καὶ τοῦτο κέκρικεν ἐν τῇ καρδίᾳ αὐτοῦ, τοῦ τηρεῖν τὴν ἑαυτοῦ παρθένον, καλῶς ποιεῖ.

1 Corinthians 15:58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
