And said, I beseech thee, O LORD God of heaven, the great and terrible God, that keepeth covenant and mercy for them that love him and observe his commandments:
And said, I beseech thee, O Lord God of heaven,.... He prayed not to the host of heaven, the sun in it, as the Persians, but to the God of it, in an humble supplicant manner:
the great and terrible God; who is to be feared, and had in reverence of all his creatures, because of his greatness and glory, being God over all, blessed for ever, and his name holy and reverend:
that keepeth covenant and mercy for them that love him, and observe his commandments; who keep them from a principle of love to him; to those he has made gracious promises in his covenant, which he truly and faithfully performs; and the consideration of these perfections in God animates and encourages good men in prayer to him.
