a child or young person: one who has been born, from a newborn infant to a young man
The word yeled names a person at the early stage of life. Its range runs from a newborn in arms (the infant Moses placed in a basket; the baby of David and Bathsheba who died in infancy) through a growing boy (the Shunamite's son who went out to the reapers and then died) to a teenager or young man (Daniel and his companions selected for Nebuchadnezzar's court; the young advisors around Rehoboam).
The two senses track this age range. The first covers the infant and child stage, where the focus is vulnerability and dependence: these are babies cried over, carried, nursed, revived. The second covers the youth and young man stage, where the focus shifts to vigor, inexperience, or inexpert counsel: the "young men who grew up with" Rehoboam, the "youths" set apart for royal education in Babylon.
The word shares its root with the verb ילד (to bear, to beget) and carries a sense of "one born": a person whose origin in birth is still in view. Animals' young are also described with this word (Job 38:41; 39:3), reinforcing the basic sense of offspring, one newly produced. The closely related word ולד (walad), an archaic alternate spelling, carries the same meaning and appears once (Genesis 11:30: "she had no child").
