In Exodus 32:20, see Strewed.

'To give provender to his donkey,' as in Genesis 42:27, signifies reflection upon scientific ideas, because 'provender' is the food with which donkeys are fed, consisting of straw and chaff, and so it denotes all reflection on scientific ideas, for reflection principally feeds them. 'Provender' signifies the good of scientific truths.
