“at the turning of days.” This is an idiom for the turning of the year, or about a year later. The Hebrew idioms about the turning of days were a godly reminder of the “wheel of life”—birth, growth, death—that is the essence of life on earth (cp. James 3:6). Here, the days turn and Samuel is born. Eventually, he will grow, marry, and have children of his own, then age and die. Samuel’s godly mother Hannah also aged and died, but she is not mentioned again after 1 Sam. 2:21.
