SEV Biblia, Chapter 9:4
no sea que, si vinieren conmigo macedonios, y os hallaren desprevenidos, nos avergoncemos nosotros, por no decir vosotros, de esta nuestra confianza.
John Gill's Bible Commentary
Ver. 4. Lest haply if they of Macedonia come with me , etc..] The apostle had determined to come himself, though he was afterwards prevented by Providence, but could not be certain of the coming of the Macedonian brethren with him; however, as it was probable that some of them would come, whose hearts were so much in this work, therefore he judged it fit and proper to send the brethren before hand, in case they should come: and find you unprepared ; not so ready for this service as had been boasted of, and the collection not finished, which had been begun a year ago. We (that we say not, ye) should be ashamed in this same confident boasting ; or in this same substance, or subsistence of boasting: a boasting, which, he thought, they had the most solid and substantial ground and foundation to proceed upon; which, should it come to nothing, must cause shame both in the apostles, who had so largely, and with so much assurance, boasted of them; and in the Corinthians, who must be put to the blush, when it should be told them how much they had been boasted of with respect to their readiness, and yet were unprepared: so tljwt , hope, expectation, confidence, is rendered by the Septuagint kauchma , boasting, ( Proverbs 11:7) and in ( Psalm 39:5) upostasiv , the word here used. And some copies, and also the Vulgate Latin version, only read, in this substance, or glorying, and leave out boasting as superfluous.
Matthew Henry Commentary
Verses 1-5 - When we would have others do good, we must act toward them prudentl and tenderly, and give them time. Christians should consider what is for the credit of their profession, and endeavour to adorn the doctrin of God their Saviour in all things. The duty of ministering to the saints is so plain, that there would seem no need to exhort Christian to it; yet self-love contends so powerfully against the love of Christ that it is often necessary to stir up their minds by way of remembrance.

Vincent's NT Word Studies
4. Confident boasting (upostasei). Primarily something put under, foundation, ground; so substance (sub, stans, standing under), substantial quality: thence steadiness, confidence. Compare Heb. iii. 14; xi. 1. In the Septuagint the word represents fifteen different Hebrew words.
Robertson's NT Word Studies
9:4 {If there come with me any of Macedonia and find you unprepared} (ean elqwsin sun emoi makedones kai heurwsin humas aparaskeuastous). Condition of third class (undetermined, but stated as a lively possibility) with ean and the second aorist active subjunctive (elqwsin, heurwsin), a bold and daring challenge. aparaskeuastos is a late and rare verbal adjective from paraskeuazw with a privative, only here in the N.T. {Lest by any means we should be put to shame} (me pws kataiscunqwmen hemeis). Negative purpose with first aorist passive subjunctive of kataiscunw (see on 7:14) in the literary plural. {That we say not, ye} (hina me legwmen humeis). A delicate syntactical turn for what he really has in mind. He does wish that they become ashamed of not paying their pledges. {Confidence} (hupostasei). this word, common from Aristotle on, comes from hufistemi, to place under. It always has the notion of substratum or foundation as here; #11:17; Heb 1:3. The papyri give numerous examples (Moulton and Milligan's _Vocabulary_) of the word for "property" in various aspects. So in #Heb 11:1 "faith is the title-deed of things hoped for." In the LXX it represents fifteen different Hebrew words.
