'Undertake' in the Bible

You may lend with interest to a foreigner, but not to your fellow Israelite; if you keep this command the Lord your God will bless you in all you undertake in the land you are about to enter to possess.

"The Lord will send on you a curse, confusing you and opposing you in everything you undertake until you are destroyed and quickly perish because of the evil of your deeds, in that you have forsaken me.
