Psalms 27:10

כִּי אָבִי וְאִמִּי עֲזָבוּנִי ה’ יַאַסְפֵנִי

Though my father and mother forsake me, G-d will gather me in.

Why would one’s parents abandon him? Rashi tells us that this actually refers to one’s conception. A person’s parents engaged in the marital act for their own enjoyment, then they each went their own way and did their own thing. It was G-d who safeguarded that tiny drop and guided it through its fetal development to birth.
