'Temporary' in the Bible

“Hear my prayer, O Lord, and listen to my cry;Do not be silent at my tears;For I am Your temporary guest,A sojourner like all my fathers.

When there were only a few men in number,Very few [in fact], and strangers in it;

I am a stranger on the earth;Do not hide Your commandments from me.

The Lord protects the strangers;He supports the fatherless and the widow;But He makes crooked the way of the wicked.
