When you want people to help you with your plan be prepared by having all of the answers to their questions.
Read: Nehemiah 2:7-9
7 I also said to the king, “If it please the king, let me have letters addressed to the governors of the province west of the Euphrates River,[a] instructing them to let me travel safely through their territories on my way to Judah. 8 And please give me a letter addressed to Asaph, the manager of the king’s forest, instructing him to give me timber. I will need it to make beams for the gates of the Temple fortress, for the city walls, and for a house for myself.” And the king granted these requests, because the gracious hand of God was on me.
9 When I came to the governors of the province west of the Euphrates River, I delivered the king’s letters to them. The king, I should add, had sent along army officers and horsemen[b] to protect me.
