Single sisters now have many opportunities to expand their ministry by pioneering, moving to where the need is greater, working with the Local Design/​Construction program, and applying for the School for Kingdom Evangelizers. Some are even able to attend Gilead School. Older women, though unable to do many of those things, are also a blessing to the congregation. How we love these dear sisters! Some may not be able to do as much as they once did in God’s service, but they can still show courage and go to work. For example, an older sister needs courage if she is asked to talk to a younger sister about modest dress. She will not scold the sister about her choice of clothing, but she may be able to encourage the younger one to consider how her choice of clothing may affect others. (1 Tim. 2:9, 10) Such loving expressions of concern may have a positive effect. w17.09 31-32 ¶17-18

A flying scroll, a woman sealed inside a container, and two women soaring in the wind with wings like those of storks​—such dramatic images are found in the book of Zechariah. (Zech. 5:1, 7-9) Why did Jehovah give these striking visions to his prophet? Zechariah’s sixth and seventh visions are a sober warning to those who persist in dishonest ways, a reminder that Jehovah does not tolerate wrongdoing. On the part of his sincere worshippers, there must be a genuine hatred of wickedness. These accounts are also a loving reassurance from our heavenly Father. If we diligently work to be the sort of people who have God’s approval and protection, we will not have to face a death-dealing curse. Rather, Jehovah will gladly bless us. All our struggles to remain clean in a world full of wickedness will be worthwhile. We can be sure that we can succeed with Jehovah’s help! w17.10 21 ¶1; 25 ¶19

The six cities of refuge were easy to access. Jehovah commanded Israel to distribute the cities evenly on both sides of the Jordan River. Why? So that any fugitive could find refuge quickly and conveniently. (Num. 35:12-14) Roads leading to the cities of refuge were kept in good repair. (Deut. 19:3) According to Jewish tradition, guideposts were erected to direct fugitives to the cities. Since the cities of refuge were available, an unintentional manslayer was not forced to flee to a foreign land, where he might be tempted to take up false worship. Think of it: Jehovah​—the very One who had mandated capital punishment for willful murderers—​gave unintentional manslayers ample opportunity to receive compassion and protection! “Every thing was made as plain, as simple, and as easy as possible,” wrote one commentator. Jehovah is not a heartless judge who is eager to punish his servants. Rather, he is “rich in mercy.”​—Eph. 2:4. w17.11 14 ¶4-5

With the establishment of the Christian congregation, music continued to be a prominent feature of true worship. On the most important night in human history, Jesus included the singing of songs after the institution of the Lord’s Evening Meal. First-century Christians set a pattern of praising God together in song. Even though they often met in private homes, the modest surroundings for worship did not diminish their zeal for singing to Jehovah. Under inspiration, the apostle Paul directed his Christian brothers: “Keep on teaching and encouraging one another with psalms, praises to God, spiritual songs sung with gratitude, singing in your hearts to Jehovah.” (Col. 3:16) The songs in our songbook are truly “spiritual songs [to be] sung with gratitude.” They are a part of the spiritual food provided by “the faithful and discreet slave.”​—Matt. 24:45. w17.11 4 ¶7-8
