“But if any widow have children or nephews, let them learn first to shew piety at home, and to requite their parents: for that is good and acceptable before God.”
King James Version (KJV)
5:4 Let these learn to requite their parents - For all their former care, trouble, and expense.
1Ti 5:4 But if any widow hath children or nephews. These must support them, and thus "show piety at home". "Nephews" is better rendered "grandchildren", as in the Revised Version.
