'Three year old' in the Bible

The LORD responded, "Bring me a three-year-old cow, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon."

Then, when she had weaned him, she brought him up with her to Shiloh, along with a three-year-old bull, an ephah of flour, and a skin of wine. She brought him to the house of the LORD at Shiloh, and the boy was young.

From the outcry at Heshbon even to Elealeh, even to Jahaz they have raised their voice, from Zoar even to Horonaim and Eglath-shelishiyah; for even the waters of Nimrim will become desolations.
