It should be noted that there are 9 different kinds of angels, and they're each ranked in how close they are to God. The ringed ones (Orphanim) are on the more powerful end of the spectrum, while the typical winged humanoids are on the lower end. So yes, both images are accurate to the description of angels.

Assuming Google Translate is correct, the biblical angel is saying something along the lines of "Please be gentle … stupid."
