After completed, we acknowledge it was done with the help of the Lord

Nehemiah 6:15-7:1
In 52 days the wall was completed. because their enemies realized that this work had been done with the help of our God.
The nobles of Judah kept coming to Tobiah and other enemies, since their son had married the daughter of their enemies. So these nobles kept reporting to Nehemiah their good deeds and telling them what Nehemiah said.
Why?
Under two months (August/September), the work having been done in the summer heat, the walls are finished- such a fantastic achievement that even Israel's enemies are forced to acknowledge God's hand in it.
One threat from within. These reveal a disloyalty on the part of leading Jews which jeopardized危害 the whole effort.
No any God's word be mentioned in this Nehemiah, but people know that it is the blessing of the Lord let the wall be completed within 52 days.
How?
The blessing of the Lord may be no word or no sign but strengthened our hands, keep everything going on and completed. Even there were intimidation or rumor or track, keep the way of the Lord.
