I Samuel 2:18-21 Samuel Is Clothed For Ministry.
As soon as Samuel was weaned he ministered before the LORD, and he did so “wearing a linen ephod” (v. 18 Cf. 2:11; 3:1). The ephod was part of the garments wore by the priesthood, as prescribed by the law (Ex. 28:4-14), so also was the robe (v. 19 Ex. 28:31). The robe was to be all blue, which was symbolic for the word. We are not told whether the robe made by Hannah each year was made of blue, but it is a likely assumption. No doubt they brought other clothing and such with each visit, but this particular robe is mentioned along with the ephod. For the gift of their firstborn, Eli the priest would bless the couple every year they came to sacrifice with the blessing of more covenant children (v. 20). “And the LORD visited Hannah, so that she conceived and bore three sons and two daughters. Meanwhile the child Samuel grew before the LORD.” (v. 21)
