The sign of an angel is love. Angels play the harp. In size, their harps are small. Some of the harps that we see are much larger than angel's harps. Their harps do not have as many strings as the harps that we have.
Angels do sing, but they are more oriented towards instrumental performance.
They like music more than words and melodies. If the woman is unwilling to come back with you, then you will be released from this oath of mine. Only do not take my son back there. As soon as we think of an angel, we imagine someone who is sweet, delicate, subtle and bright. This is the angelic touch.
