Genesis 21:12

¹² and God saith unto Abraham, `Let it not be wrong in thine eyes because of the youth, and because of thy handmaid: all that Sarah saith unto thee -- hearken to her voice, for in Isaac is a seed called to thee.

Fear not

Fear not, as in Genesis 20:8, signifies aversion. To fear signifies to disbelieve or not to have faith and love, as in Isaiah 43:1, 5; 44:8; Mark 5:36; Luke 1:73, 75; 4:40; 8:49; 12:7, 32.

Fear not, as in Revelation 1:17; Daniel 10:5, 12; Matthew 17:5, 7; 28:10, etc., signifies resuscitation to life, and at the same time adoration from the most profound humiliation.
