'Working' in the Bible

Thy tongue deviseth very wickedness, Like a sharp razor, working deceitfully.

Yet God is my King of old, Working salvation in the midst of the earth.

Thus saith the Lord Jehovah: The gate of the inner court that looketh toward the east shall be shut the six working days; but on the sabbath day it shall be opened, and on the day of the new moon it shall be opened.

Behold ye among the nations, and look, and wonder marvellously; for I am working a work in your days, which ye will not believe though it be told you.
