Zechariah 4:10

The people would be ashamed that they had despised the rebuilding project as insignificant (cf. Ezra 3:12; Haggai 2:3). [Note: See Wayne O. McCready, "The ’Day of Small Things’ vs. the Latter Days: Historical Fulfillment or Eschatological Hope?" in Israel’s Apostasy and Restoration: Essays in Honor of Roland K. Harrison, pp. 223-36.] The Lord Himself was glad to see Zerubbabel building with his plumb line as His omniscient eyes surveyed all that was happening in the world (cf. Zechariah 3:9; 2 Chronicles 16:9). The Hebrew words translated "plumb line" may mean "separated [i.e., chosen] stone." In this case the idea would be that the Lord, in addition to His people, would rejoice when He saw the capstone put in place (cf. Zechariah 4:7; Ezra 6:16-22). Now His people could serve Him as He purposed.

"Bible history is the record of God using small things. When God wanted to set the plan of salvation in motion, He started with a little baby named Isaac (Genesis 21). When He wanted to overthrow Egypt and set His people free, He used a baby’s tears (Exodus 2:1-10). He used a shepherd boy and a sling to defeat a giant (1 Samuel 17) and a little lad’s lunch to feed a multitude (John 6). He delivered the Apostle Paul from death by using a basket and a rope (Acts 9:23-25). Never despise the day of small things, for God is glorified in small things and uses them to accomplish great things." [Note: Wiersbe, p. 456.]
