What was the consequence of "Tovosav Hayu Omerim Lefanai"?

What do we learn from "u'Devarai Hayu Motzi'im Lo"?
Ibn Ezra: This is read with "Igros Shalach Toviyah Leyar'eni." I told them that Toviyah sends letters to scare me, and they told this to him.
Malbim: Because they considered him to be good, they revealed my secrets to him. He had spies amidst Yisrael! Therefore, I guarded greatly even after the wall was completed, and I did not fear the surrounding Goyim.
What was the consequence of "Igros Shalach Toviyah Leyar'eni"?
Rashi: He constantly sent letters to me to scare me, not to build the wall.
