(5.) This God is Israel's God in covenant, and the felicity of every Israelite indeed. Therefore let the house of Israel cleave to him, and not forsake him to embrace idols; for, if they do, they certainly change for the worse, for (v. 16) the portion of Jacob is not like them; their rock is not as our rock (Deut. xxxii. 31), nor ours like their mole-hills. Note, [1.] Those that have the Lord for their God have a full and complete happiness in him. The God of Jacob is the portion of Jacob; he is his all, and in him he has enough and needs no more in this world nor the other. In him we have a worthy portion, Ps. xvi. 5. [2.] If we have entire satisfaction and complacency in God as our portion, he will have a gracious delight in us as his people, whom he owns as the rod of his inheritance, his possession and treasure, with whom he dwells and by whom he is served and honoured. [3.] It is the unspeakable comfort of all the Lord's people that he who is their God is the former of all things, and therefore is able to do all that for them, and give all that to them, which they stand in need of. Their help stands in his name who made heaven and earth. And he is the Lord of hosts, of all the hosts in heaven and earth, has them all at his command, and will command them into the service of his people when there is occasion. This is the name by which they know him, which they first give him the glory of and then take to themselves the comfort of. [4.] Herein God's people are happy above all other people, happy indeed, bona si sua norint—did they but know their blessedness. The gods which the heathen pride, and please, and so portion themselves in, are vanity and a lie; but the portion of Jacob is not like them.
