The king supposed that there was a meaning in those looks and words of his, that he had a favour to ask of him, and therefore encourages him to it; or the king of himself moved this, as being desirous of doing anything for him he would propose, to make him easy: so I prayed to the God of heaven; secretly, in an ejaculatory way, giving him thanks for thus disposing the king's heart towards him, and entreating he might be directed what to ask, and in a proper manner, and that he might succeed.
