Philo of Alexandria (c 20 BCE - c 50 CE) Allegorical Interpretation 1.2.2
"'And God finished on the sixth day His works which He had made' (Genesis 2:2). It is quite foolish to think that the world was created in six days in a space of time at all. Why? Because every period of time is a series of days and nights, and these can only be made such by the movement of the sun as it goes over and under the earth; but the sun is part of heaven, so that time is confessedly more recent than the world. It would therefore be correct to say that the world was not made in time, but that time was formed by means of the world, for it was heaven's movement that was the index of the nature of time."
Allegorical Interpretation 2.7.19
"'And God brought a trance upon Adam, and he fell asleep; and He took one of his sides' (Genesis 2:21) and what follows. These words in their literal sense are of the nature of a myth [mythodes]. For how could anyone admit that a woman, or a human being at all, came into existence out of a man's side?"
Allegorical Interpretation I Part 2.31.97
And the recommendations that he addresses to him are as follows: "Of every tree that is in the Paradise thou mayest freely Eat." He exhorts the soul of man to derive advantage not from one tree alone nor from one single virtue, but from all the virtues; for eating is a symbol of the nourishment of the soul, and the soul is nourished by the reception of good things, and by the doing of praiseworthy actions.
On the Creation 56.154
And these statements appear to me to be dictated by a philosophy which is symbolical rather than strictly accurate. For no trees of life or of knowledge have ever at any previous time appeared upon the earth, nor is it likely that any will appear hereafter. But I rather conceive that Moses was speaking in an allegorical spirit, intending by his paradise to intimate the dominant character of the soul, which is full of innumerable opinions as this figurative paradise was of trees. And by the tree of life he was shadowing out the greatest of the virtues namely, piety towards the gods, by means of which the soul is made immortal; and by the tree which had the knowledge of good an evil, he was intimating that wisdom and moderation, by means of which things, contrary in their nature to one another, are distinguished.
Josephus Antiquities of the Jews Preface 4
I exhort, therefore, my readers to examine this whole undertaking in that view; for thereby it will appear to them, that there is nothing therein disagreeable either to the majesty of God, or to his love to mankind; for all things have here a reference to the nature of the universe; while our legislator [Moses] speaks some things wisely, but enigmatically, and others under a decent allegory, but still explains such things as required a direct explication plainly and expressly. However, those that have a mind to know the reasons of every thing, may find here a very curious philosophical theory, which I now indeed shall wave the explication of; but if God afford me time for it, I will set about writing it after I have finished the present work. I shall now betake myself to the history before me, after I have first mentioned what Moses says of the creation of the world, which I find described in the sacred books after the manner following.
Antiquities of the Jews 1.1.2
Moreover, Moses, after the seventh day was over begins to talk philosophically; and concerning the formation of man, says thus: : That God took dust from the ground, and formed man, and inserted in him a spirit and a soul.
