'Keep' in the Bible

I applied my mind to seek and explore through wisdom all that is done under heaven. God has given people this miserable task to keep them occupied.

a time to search and a time to count as lost;a time to keep and a time to throw away;

I have seen the task that God has given people to keep them occupied.

Also, if two lie down together, they can keep warm; but how can one person alone keep warm?

Keep the king’s command because of your oath made before God.

When all has been heard, the conclusion of the matter is: fear God and keep His commands, because this is for all humanity.
