'Critically' in the Bible

During this time Hezekiah became critically ill, and he prayed to the LORD. The LORD spoke to him and gave him a sign.

“You also put my feet in the stocks [as punishment]And [critically] observe all my paths;You set a circle and limit around the soles of my feet [which I must not overstep],

each one’s work will be clearly shown [for what it is]; for the day [of judgment] will disclose it, because it is to be revealed with fire, and the fire will test the quality and character and worth of each person’s work.

We must not tempt the Lord [that is, test His patience, question His purpose or exploit His goodness], as some of them did—and they were killed by serpents.

‘I know your deeds and your toil, and your patient endurance, and that you cannot tolerate those who are evil, and have tested and critically appraised those who call themselves apostles (special messengers, personally chosen representatives, of Christ), and [in fact] are not, and have found them to be liars and impostors;

Fear nothing that you are about to suffer. Be aware that the devil is about to throw some of you into prison, that you may be tested [in your faith], and for ten days you will have tribulation. Be faithful to the point of death [if you must die for your faith], and I will give you the crown [consisting] of life.
