TEHILLIM 39

4 My lev became hot within me;

while I was musing the eish burned;

then I spoke with my leshon:

5 Hashem, make me to know mine end,

and the measure of my yamim, what it is;

that I may have da’as of how chadel (fleeting, frail) I am.

6 Hinei, Thou hast made my yamim as a handbreadth,

and mine lifespan is as nothing before Thee;

verily kol adam stand as kol hevel (altogether vanity).

Selah
