'Possibly' in the Bible

For what thanksgiving on your behalf can we possibly offer to God in return for all the joy which fills our souls before our God for you,

For this we say to you by the word of the Lord, that we who are alive, who remain until the Lord's coming, will not possibly precede those who have fallen asleep.

Whenever they say "Peace and security," then sudden destruction will overtake them like the birth pains of {a pregnant woman}, and they will not possibly escape.
