'Firstling' in the Bible

And you shall bring there your burnt offerings and your sacrifices and your tithes and {your donations} and your votive gifts and your freewill offerings and the firstling of your herd and your flock.

And you shall eat {before} Yahweh your God in the place that he will choose to make to dwell his name there the tithe of your grain, your wine and your olive oil and the firstling of your herd and your flock, so that you may learn to revere Yahweh your God {always}.

All the firstling males that come of thy herd and of thy flock thou shalt sanctify unto the LORD thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.

His glory is like the firstling of his bullock, and his horns are like the horns of unicorns: with them he shall push the people together to the ends of the earth: and they are the ten thousands of Ephraim, and they are the thousands of Manasseh.
