'Firmly' in the Bible

Solomon sat on the throne of David his father; and his kingdom was firmly established.

The earth and all its inhabitants quake. I firmly hold its pillars. Selah.

The evil deeds of the wicked ensnare him. The cords of his sin hold him firmly.

Behold, Yahweh will overcome you and hurl you away violently. Yes, he will grasp you firmly.

by which also you are saved, if you hold firmly the word which I preached to you -- unless you believed in vain.

and not holding firmly to the Head, from whom all the body, being supplied and knit together through the joints and ligaments, grows with God's growth.

Test all things, and hold firmly that which is good.

"I know your works and where you dwell, where Satan's throne is. You hold firmly to my name, and didn't deny my faith in the days of Antipas my witness, my faithful one, who was killed among you, where Satan dwells.

Nevertheless, hold that which you have firmly until I come.

I am coming quickly! Hold firmly that which you have, so that no one takes your crown.
