Youth. The first occurrence of this word in v. 9, Heb. yalduth, has reference to youthfulness; the second, Heb. bachur, to the prime of life. The first appears again in Ps. 110:3; the second in Eccl. 12:1.
Thine heart. All legitimate desires and needs are to be met, but debauchery and overindulgence are to be condemned and avoided.
