Charles H. Spurgeon on Psalms 119:19

I am a stranger in the earth. This is meant for a plea. By divine command men are bound to be kind to strangers, and what God commands in others he will exemplify in himself. The Psalmist was a stranger for God's sake, else had he been as much at home as worldlings are: he was not a stranger to God, but a stranger to the world, a banished man so long as he was out of heaven. Therefore he pleads,

Hide not thy commandments from me. If these are gone, what have I else? Since nothing around me is mine, what can I do if I lose thy word? Since none around me know or care to know the way to thyself, what shall I do if I fail to see thy commands, by which alone I can guide my steps to the land where thou dwellest? David implies that God's commands were his solace in his exile: they reminded him of home, and they showed him the way thither, and therefore he begged that they might never be hidden from him, by his being unable either to understand them or to obey them. If spiritual light be withdrawn the command is hidden, and this a gracious heart greatly deprecates. What would be the use of opened eyes if the best object of sight were hidden from their view? While we wander here we can endure all the ills of this foreign land with patience if the word of God is applied to our hearts by the Spirit of God; but if the heavenly things which make for our peace were hid from our eyes we should be in an evil case, in fact, we should be at sea without a compass, in a desert without a guide, in an enemy's country without a friend.

This prayer is a supplement to "open thou mine eyes", and, as the one prays to see, the other deprecates the negative of seeing, namely, the command being hidden, and so out of sight. We do well to look at both sides of the blessing we are seeking, and to plead for it from every point of view. The prayers are appropriate to the characters mentioned: as he is a servant he asks for opened eyes that his eyes may ever be towards his Lord, as the eyes of a servant should be; as a stranger he begs that he may not be strange to the way in which he is to walk towards his home. In each case his entire dependence is upon God alone.

Note how the third of the second octave (11) has the same keyword as this third of the third octave: "Thy word have I hid, ""Hide not thy commandments from me." This invites a meditation upon the different senses of hiding in and hiding from.
