Proverbs 31:18

¹⁶ She appraises a field and buys it; from her earnings she plants a vineyard.

¹⁷ She girds herself with strength and shows that her arms are strong.

She sees that her gain is good, and her lamp is not extinguished at night.

¹⁹ She stretches out her hands to the distaff and grasps the spindle with her fingers.

²⁰ She opens her arms to the poor and reaches out her hands to the needy.

Do read the surrounding verses too, because the context often says more than a single verse.
