wear yourself out to get rich

Do not wear yourself out to get rich;
do not trust your own cleverness.
5 Cast but a glance at riches, and they are gone,
for they will surely sprout wings
and fly off to the sky like an eagle.?

He(Jesus) would have them cease to indulge in hoarding up earthly treasures, in spending money upon luxuries, and in surrounding themselves with all those things which they do not need. He would not have them destroy spiritual power, but directs their attention to heavenly things. {LHU 128.2}
He urges that men should seek more earnestly and continually for the bread of life than for the bread which perishes. He says, "Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed." . . .LHU 128.3
