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.

144. As to 'calling by name' meaning recognizing their nature, it must be realized that the ancients understood nothing else by 'a name than the essential nature of a real thing, and by 'seeing and calling them by name' recognizing the nature of such. This was why they gave their sons and daughters names in keeping with the things that were meant by them; for there was something unique to every name, as a means of knowing the origin and nature of those children, as will also be seen later on where, in the Lord's Divine mercy, the twelve sons of Jacob are dealt with. Since therefore a name embodied a person's origin and nature nothing else was meant by 'calling by name'. This manner of speaking was customary among them; but anyone who does not understand is sure to wonder whether they do have these meanings.
