'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.
