Angels are exact and careful observers and eyewitnesses of our behavior and deportment in the public ordinances. To this end were the curtains of the tabernacle pictured: full of cherubim to signify that about our solemn meetings, whole troops of angels take notice of our behavior.

Yea, how spiritual and heavenly should we be if our hearts were but fixed on these glorious angels?Communion with Angels, 100
