Sirach 47:2-4

Revised Standard Version

² As the fat is selected from the peace offering,
    so David was selected from the sons of Israel.
³ He played with lions as with young goats,
    and with bears as with lambs of the flock.
⁴ In his youth did he not kill a giant,
    and take away reproach from the people,
when he lifted his hand with a stone in the sling
    and struck down the boasting of Goliath?
