'Suggestion' in the Bible

And this suggestion seemed good to the king and the captains; and the king did as Memucan said;

And let the girl who is pleasing to the king be queen in place of Vashti. And the king was pleased with this suggestion; and he did so.

Then his wife Zeresh and all his friends said to him, Let a pillar, fifty cubits high, be made ready for hanging him, and in the morning get the king to give orders for the hanging of Mordecai: then you will be able to go to the feast with the king with a glad heart. And Haman was pleased with the suggestion, and he had the pillar made.
