G1476–ἑδραῖος–hedraios

But he that standeth stedfast in his heart, having no necessity, but hath power as touching in his own heart, to keep his own virgin [supplied: daughter], shall do well.

ἑδραῖος hedraios “firm”

Wherefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labor is not vain in the Lord.

ἑδραῖοι hedraioi “steadfast”

if so be that ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation under heaven; whereof I Paul was made a minister.
