'Infant' in the Bible

Now go and smite Amalek, and destroy utterly all that they have, and spare them not, but slay both man and woman, infant and suckling, ox and sheep, camel and ass.

There shall be no more thenceforth an infant of days, nor an old man that hath not completed his days; for the youth shall die a hundred years old, and the sinner being a hundred years old shall be accursed.

And now thus saith Jehovah the God of hosts, the God of Israel: Wherefore commit ye great evil against your souls, to cut off from you man and woman, infant and suckling, out of the midst of Judah, to leave you no remnant;

Mine eyes are consumed with tears, my bowels are troubled; my liver is poured upon the earth, because of the ruin of the daughter of my people; because infant and suckling swoon in the streets of the city.
