Malachi 1:8

Furthermore the priests were offering blind, lame, and sick animals as sacrifices. These were unacceptable according to the Law (Leviticus 22:18-25; Deuteronomy 15:21). The Lord asked them if this was not evil. Of course it was. They would not offer such bad animals to their governor because they would not please him, but they dared offer them to their King. The governor in view would have been one of the Persian officials who ruled over the territory occupied by Judah. Nehemiah held this position for a while, but others preceded and followed him in it. The Book of Malachi seems to date from Nehemiah’s leadership of Israel, but Nehemiah refused to receive offerings from the people (Nehemiah 5:14; Nehemiah 5:18). So the governor in view here was probably not Nehemiah. Elnathan, Yeho’ezer, and Ahzai were evidently the governors of Judah between Zerubbabel and Nehemiah. [Note: N. Avigad, "Bullae and Seals from a Post-exilic Judean Archive," Qedem 4, p. 34.]

Anything second-rate that we offer to God is inappropriate in view of who He is. This includes our worship, our ministries, our studies, physical objects, anything. The Lord is worthy of our very best offerings to Him, and we should give Him nothing less. To give Him less than our best is to despise Him. Shoddiness is an insult to God. Shoddy holy is still shoddy.
