Proverbs 7:4

Call understanding thy kinswoman— Thy relation: The LXX have it, Make wisdom thy acquaintance. "Say to wisdom, Thou art my sister, my spouse, my beloved, my inclination. Give to her thy heart, that she may preserve thee from the snares of the strange woman." The name of sister, is a name of friendship, used in scripture, between the husband and wife, and denotes the chaste love which he should have to wisdom. See the Canticles and Calmet.
