Agni, lead us on to wealth (beatitude) by a good path, thou, O God, who knowest all things! Keep far from us crooked evil, and we shall offer thee the fullest praise! (Rv. I, 189, 1.)

In plain words: The speaker prays to Agni, the god of fire, who knows everything. He asks Agni to lead us by a good path to the highest good and to keep crooked, evil ways far from us. In return, we will praise him with all our hearts.
