'Undertaken' in the Bible

And Abraham answering said, Truly, I who am only dust, have undertaken to put my thoughts before the Lord:

And he said, See now, I have undertaken to put my thoughts before the Lord: what if there are twenty there? And he said, I will have mercy because of the twenty.

And the Lord came to Sarah as he had said and did to her as he had undertaken.

And he said, O Lord, the God of my master Abraham, let me do well in what I have undertaken this day, and give your mercy to my master Abraham.

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.

And now I will send to you what my father has undertaken to give you, but do not go from the town, till the power from heaven comes to you.

And not only so, but he was marked out by the churches to go with us in the grace of this giving which we have undertaken to the glory of the Lord and to make clear that our mind was ready:

So it seemed to me wise for the brothers to go before, and see that the amount which you had undertaken to give was ready, so that it might be a cause for praise, and not as if we were making profit out of you.

So that on the Gentiles might come the blessing of Abraham in Christ Jesus; in order that we through faith might have the Spirit which God had undertaken to give.
