What was the significance of weaning a child in the Bible (Genesis 21:8)?

Answer  
  

According to Jewish custom, the time when a child is weaned is cause for celebration. A weaned child has survived the fragile stage of infancy and can now eat solid food rather than breastfeed from his or her mother.  
  

In Genesis 21:8, we read, “And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned.” Though Ishmael laughed at the celebration (Genesis 21:9\), Isaac’s parents considered this event an important occasion. They had a son who had survived the most difficult stage of childhood and could now eat on his own.  
  

According to Jewish rabbinical traditions, weaning could take place anywhere between 18 months and 5 years of age. In one important biblical parallel, Samuel was weaned prior to being taken to Eli the priest to serve the Lord. First Samuel 1:24 says, “And when she had weaned him . . . she brought him to the house of the LORD at Shiloh. And the child was young.” No exact age is given, but the weaning is mentioned, and Samuel’s youth is emphasized, so he was likely between 2 and 4 years old.  
  

High infant mortality rates existed in ancient cultures. One reason for large families was the fact that many young children did not live to adulthood. Because of the risks that infants faced, the celebration of a child’s weaning was a natural and important part of the culture. If a child had developed past the need for the physical support of a mother, then he or she had reached a new stage of life that greatly increased the likelihood of good health.  
  

Today, Jewish tradition continues the practice of celebrating the weaning of a child. Psalm 104 is often read during this time; part of that psalm says, “Bless the LORD, O my soul! O LORD my God, you are very great! You are clothed with splendor and majesty, covering yourself with light as with a garment, stretching out the heavens like a tent. He lays the beams of his chambers on the waters; he makes the clouds his chariot; he rides on the wings of the wind; he makes his messengers winds, his ministers a flaming fire” (Psalm 104:1–4\).
