According to Artapanus, writing in the second century BCE, Abraham had once taught the Egyptian Pharoah Pharethothes astrological methods. This is interesting because astrology can be considered a techincal art and not necessarily a part of worship.
I'm not sure how this connects to your question, Gubberingbody, but if true it may reflect on the fact that Abraham was using reason and rational thinking in his decision not to sacrifice his son Issac.
edit:
another interesting tidbit is that the jews largely treasured and nurtured all the children conceived and born to them whereas in contrast the Romans, for example, valued babies as fully human from when they were given a legitimate identity. Babies not legitimized in this way could be left to die or sold as a slave.
Tacitus said of the jews that they "take thought to increase their numbers, for they regard it as a crime to kill an undesired child".
Also writing in the third century BCE Hecataeus said "[Moses] required those who dwelt in the land to rear their children". This was in harmony with the commandment to "Be fruitful, and multiply"
