In Proverbs 5:18 what is meant by “your wife in your youth”?
The Bible is not priggish on sexual relation, for the wise King Solomon said:
Proverbs 5:18-19 (NRSV)
18 "Let your fountain be blessed,and rejoice in the wife of your
youth, 19 a lovely deer, a graceful doe. May her breasts satisfy you
at all times; may you be intoxicated always by her love."
The phrase "let your fountain be blessed " refers to sexual gratification, and loving satisfaction and enjoyment that a married couple have within the marital arrangement, so King Solomon rhetorically asks:
20 "Why should you be intoxicated, my son, by another woman and
embrace the bosom of an adulteress?"(Prov. 5:20 NRSV)
One should be steadfast to see life with the woman that you first married, Solomon said:
Ecclesiastes 9:9 (NASB)
9 "Enjoy life with the woman whom you love all the days of your
fleeting life which He has given to you under the sun; for this is
your reward in life and in your toil in which you have labored under
Military law exempted men from military service for one year ,in order to give happiness to his wife, and perhaps have a child because the husband may die in battle.
Deuteronomy 24:5 (NASB)
5 “When a man takes a new wife, he shall not go out with the army nor
be charged with any duty; he shall be free at home one year and shall
give happiness to his wife whom he has taken."
