'Anxious' in the Bible

“For he will be like a tree planted by the water,That extends its roots by a streamAnd will not fear when the heat comes;But its leaves will be green,And it will not be anxious in a year of droughtNor cease to yield fruit.

then the sword, which you are afraid of, will overtake you there in the land of Egypt; and the famine, about which you are anxious, will follow closely after you there in Egypt, and you will die there.
