John Gill Commentary Nehemiah 9:10

"and showedst signs and wonders upon Pharaoh, and on all his servants, and on all the people of his land; for thou knewest that they dealt proudly against them, and didst get thee a name, as it is this day." — Nehemiah 9:10 (ASV)

And showed signs and wonders upon Pharaoh, and on all his
servants, and on all the people of his land
By inflicting the ten plagues upon them:

for you know that they dealt proudly against them ;
behaved haughtily to them, and despised them, see (Exodus 18:11)

so you got yourself a name, as it is this day ;
displayed his power on Pharaoh, and his goodness to Israel, the fame of which reached all over the world, and continued to that day, see (Exodus 9:16) .
