Romans 11:18

“Boast not against the branches, etc..] Those that were broken off: the apostle would not have them vaunt it over them, despise them, and trample upon them; but pity them, and pray for and be abundantly thankful and humbled before God, under a sense of Ida sovereign and distinguishing grace, who had settled them in a Gospel church state, who were before comparable to a wild olive tree; and much less should they glory over the believing Jews, among whom they were, there being no difference between them, for they were all one in Christ Jesus: but if thou boast; but if such a vain temper of mind should prevail, he suggests they would do well to sit down and consider what little reason they had…”

“Boast not against the--rejected branches. But if thou--"do" boast--remember that thou bearest not--"it is not thou that bearest" the root, but the root thee--"If the branches may not boast over the root that bears them, then may not the Gentile boast over the seed of Abraham; for what is thy standing, O Gentile, in relation to Israel, but that of a branch in relation to the root? From Israel hath come all that thou art and hast in the family of God; for "salvation is of the Jews" (Joh 4:22).”

“Boast not ... - The tendency of people is to triumph over one that is fallen and rejected. The danger of pride and boasting on account of privileges is not less in the church than elsewhere. Paul saw that some of the Gentiles might be in danger of exultation over the fallen Jews, and therefore cautions them against it. The ingrafted shoot, deriving all its vigor and fruitfulness from the stock of another tree, ought not to boast against the branches. But if thou boast - If thou art so inconsiderate and wicked, so devoid of humility, and lifted up with pride, as to boast, yet know that there is no occasion for it. If there were occasion for boasting, it would rather be in the root or stock…”

“Boast not against the branches - Do not they do this who despise the Jews? or deny their future conversion? Romans 11:20”

“11:18 You are just a branch, not the root: By the time Paul wrote to the church in Rome, it was composed mainly of Gentiles, a common situation in the early Christian communities. This dominant role led many Gentile Christians to brag about their status, while treating Jews and their religious heritage with disdain. Paul reminds the Gentile believers that they enjoy God’s blessings only because they have been included in the one people of God, who are rooted in God’s promises to Israel.”
