4822. 'And he called his name Er' means the essential nature of that falsity. This is clear from the meaning of 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3421, namely the nature of the falsity of the Church, dealt with immediately above in 4821. The expression 'the nature of the falsity' is used because falsities differ from one another, even as truths do, so much so that the different types of falsity can hardly be counted; and each type of falsity has its own specific nature by which it is distinguished from any other. Common falsities reign among the wicked in every Church, but each person's falsity varies in keeping with the life he leads. The falsity which existed in the Jewish Church and is referred to here was falsity springing from the evil of self-love and of love of the world based on this, see 4818.

3421. 'And he called them names' means the essential nature of them. This is clear from the meaning of 'calling the names' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3237. And since calling the names or the name means the essential nature, the expression calling without the addition of 'the name' therefore means in the internal sense of the Word to be of some such particular nature, as in Isaiah,

Hear this, O house of Jacob, who are called by the name of Israel and who came out of the waters of Judah. For they are called after the city of holiness, and upon the God of Israel they place their reliance. Isaiah 48:1-2.

Here 'being called after the city of holiness' stands for being of some particular nature. And in Luke,

Behold, you will conceive in the womb and will bear a son, and you will call His name Jesus. He will be great and will be called Son of the Most High. Luke 1:31-32.

'Being called Son of the Most High' stands for His Essential Being (Esse).
