'Undertake' in the Bible

And the Lord said, See, this is what I will undertake: before the eyes of your people I will do wonders, such as have not been done in all the earth or in any nation: and all your people will see the work of the Lord, for what I am about to do for you is greatly to be feared.

At that time I said to you, I am not able to undertake the care of you by myself;

How is it possible for me by myself to be responsible for you, and undertake the weight of all your troubles and your arguments?

And so the Lord has said, You have not given ear to me and undertaken publicly, every man to let loose his countryman and his neighbour: see, I undertake to let loose against you the sword and disease and need of food; and I will send you wandering among all the kingdoms of the earth.
