Some translations prefer to set apart quotations of the Old Testament. The ULB and many other English translations indent the lines of 2:6, 7, 8, 10, 22, which are quotations from the Old Testament.

#### Important figures of speech in this chapter ####
##### Milk and solid food #####
This is an image used to describe maturity in Christ. It compares the immature Christian to a baby who is only able to drink milk. Immature Christians are not mature enough to handle solid foods, which are the more complex teachings about Jesus. Instead, they have chosen not to grow so they remain like babies who only drink milk, the simpler and more basic teachings about Jesus. (See: [[rc://en/ta/man/translate/figs-metaphor]])

##### "You are now the people of God" #####
Some scholars believe this indicates the church has replaced Israel in the plans of God. Other scholars believe there are more than one "people of God." (See: [[rc://en/tw/dict/bible/kt/peopleofgod]]).
