(37) If heaven above can be measured . . .--The thought of the preceding verse is reproduced with a slight modification of meaning. Over and above the idea, as stated above, that the stability of nature is a parable of the steadfastness of God's laws and purposes in the spiritual world, there is implied a feeling, like that of Romans 11:33, that man's finite intellect cannot fathom His modes of working out that purpose any more than it can measure what to the prophet's mind were the illimitable heaven and the unfathomable earth.

Verse 37. - Thus edith the Lord. "It is not without meaning that the prophet so frequently repeats: 'Thus saith the Lord.' This formed the Α and Ω; his word was the sole ground of hope for Israel. Apart from it, despair was as reasonable as now it was unreasonable" (Hengstenberg).

31:35-40 As surely as the heavenly bodies will continue their settled course, according to the will of their Creator, to the end of time, and as the raging sea obeys him, so surely will the Jews be continued a separate people. Words can scarcely set forth more strongly the restoration of Israel. The rebuilding of Jerusalem, and its enlargement and establishment, shall be an earnest of the great things God will do for the gospel church. The personal happiness of every true believer, as well as the future restoration of Israel, is secured by promise, covenant, and oath. This Divine love passes knowledge; and to those who take hold upon it, every present mercy is an earnest of salvation.Thus saith the Lord, if heaven above can be measured,.... Either the space between the highest heavens and the earth; or the extent of the heavens, from one end of them to the other, which cannot be done by man; so the Targum,

"as it is impossible that man should know the measure of the heavens above;''

otherwise it is measured by the Lord, for he hath "meted out heaven with a span", Isaiah 40:12;

and the foundations of the earth searched out beneath: so as to be known what they are, or on what they are fastened, since the earth is hung upon nothing, Job 38:6;

I will also cast off all the seed of Israel for all that they have done, saith the Lord; as the former cannot be, so neither the latter; when there was a very great rejection of the Jews for their disbelief of the Messiah, they were not all cast off; the Apostle Paul was an instance to the contrary, and so were others: "the remnant according to the election of grace"; and there is a time coming when all Israel shall be saved, Romans 11:5; nor shall any of the spiritual Israel be cast off by him, or cast away from him, so as to perish; the Israel, whom God foreknew, is chosen, redeemed, and whom he calls by his grace; no, not for all the sins and transgressions they have been guilty of, however they may deserve it. The reasons are, because of his unchangeable love to them; his unalterable covenant with them; the satisfaction his son has made for them; and the free and full pardon of their sins, which he has granted to them.
