First Reading for Trinity Sunday – Year B - Daily Catholic Mass Reading

Moses said to the people: "Ask now of the days of old, before your time, ever since God created man upon the earth; ask from one end of the sky to the other:

Did anything so great ever happen before? Was it ever heard of? Did a people ever hear the voice of God speaking from the midst of fire, as you did, and live?

Or did any god venture to go and take a nation for himself from the midst of another nation, by testings, by signs and wonders, by war, with strong hand and outstretched arm, and by great terrors,
all of which the LORD, your God, did for you in Egypt before your very eyes?

This is why you must now know, and fix in your heart, that the LORD is God in the heavens above and on earth below, and that there is no other.

You must keep his statutes and commandments that I enjoin on you today, that you and your children after you may prosper, and that you may have long life on the land which the LORD, your God, is giving you forever."
