'Three year old' in the Bible

So He said to him, “Bring Me a three year old heifer, and a three year old female goat, and a three year old ram, and a turtledove, and a young pigeon.”

Now when she had weaned him, she took him up with her, with a three-year-old bull and one ephah of flour and a jug of wine, and brought him to the house of the Lord in Shiloh, although the child was young.
